Herein, we report the synthesis of Zn-doped NiO heterostructure (ZnNiO) catalysts at room temperature via a coprecipitation method followed by drying (at 80 °C, 6 h) and calcination at an elevated temperature of 400 °C for 5 h under three distinct conditions, namely, air, N2, and vacuum. The vacuum-synthesized catalyst demonstrates a low overpotential of 88 mV at −10 mA cm–2 and a small Tafel slope of 73 mV dec–1 suggesting relatively higher charge transfer kinetics for hydrogen evolution reactions (HER) compared with the specimens synthesized under N2 or O2 atmosphere. It also demonstrates an oxygen evolution (OER) overpotential of 260 mV at 10 mA cm–2 with a low Tafel slope of 63 mV dec–1. In a full-cell water-splitting device, the vacuum-synthesized ZnNiO heterostructure demonstrates a cell voltage of 1.94 V at 50 mA cm–2 and shows remarkable stability over 24 h at a high current density of 100 mA cm–2. It is also demonstrated in this study that Zn-doping, surface, and interface engineering in transition-metal oxides play a crucial role in efficient electrocatalytic water splitting. Also, the results obtained from density functional theory (DFT + U = 0–8 eV), where U is the on-site Coulomb repulsion parameter also known as Hubbard U, based electronic structure calculations confirm that Zn doping constructively modifies the electronic structure, in both the valence band and the conduction band, and found to be suitable in tailoring the carrier’s effective masses of electrons and holes. The decrease in electron’s effective masses together with large differences between the effective masses of electrons and holes is noticed, which is found to be mainly responsible for achieving the best water-splitting performance from a 9% Zn-doped NiO sample prepared under vacuum."}],"oa_version":"None","scopus_import":"1","intvolume":" 7","month":"01","publication_status":"published","publication_identifier":{"issn":["2574-0962"]},"language":[{"iso":"eng"}],"volume":7,"issue":"1","citation":{"mla":"Kiran, Gundegowda Kalligowdanadoddi, et al. “Interface Engineering Modulation Combined with Electronic Structure Modification of Zn-Doped NiO Heterostructure for Efficient Water-Splitting Activity.” ACS Applied Energy Materials, vol. 7, no. 1, American Chemical Society, 2024, pp. 214–29, doi:10.1021/acsaem.3c02519.","ieee":"G.

Despite a multitude of studies, the major mechanisms and key intermediates involved in the dehydrogenation process of formic acid remain a great topic of debate due to ambiguous adsorbate interactions. In this research, we develop an advanced microkinetic model based on first-principles calculations, accounting for adsorbate–adsorbate interactions. Our study unveils a comprehensive mechanism for the Pd (1 1 1) surface, highlighting the significance of coverage effects in formic acid dehydrogenation. Our findings unequivocally demonstrate that H coverage on the Pd (1 1 1) surface renders formic acid more susceptible to decompose into H2 and CO2 through COOH intermediates. Consistent with experimental results, the selectivity of H2 in the decomposition of formic acid on the Pd (1 1 1) surface approaches 100 %. Considering the influence of H coverage, our kinetic analysis aligns perfectly with experimental values at a temperature of 373 K."}],"oa_version":"None","author":[{"last_name":"Yao","full_name":"Yao, Zihao","first_name":"Zihao"},{"first_name":"Xu","last_name":"Liu","full_name":"Liu, Xu"},{"full_name":"Bunting, Rhys","orcid":"0000-0001-6928-074X","last_name":"Bunting","first_name":"Rhys","id":"91deeae8-1207-11ec-b130-c194ad5b50c6"},{"full_name":"Wang, Jianguo","last_name":"Wang","first_name":"Jianguo"}],"article_processing_charge":"No","title":"Unravelling the reaction mechanism for H2 production via formic acid decomposition over Pd: Coverage-dependent microkinetic modeling","citation":{"mla":"Yao, Zihao, et al. “Unravelling the Reaction Mechanism for H2 Production via Formic Acid Decomposition over Pd: Coverage-Dependent Microkinetic Modeling.” Chemical Engineering Science, vol. 291, 119959, Elsevier, 2024, doi:10.1016/j.ces.2024.119959.","ieee":"Z.

However, the library of RT high-performance materials is limited. Traditional high-temperature synthetic methods constrain the range of materials achievable, hindering the ability to surpass crystal structure limitations and engineer defects. Here, a solution-based synthetic approach is introduced, enabling RT synthesis of powders and exploration of densification at lower temperatures to influence the material's microstructure. The approach is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated that the concentration of Ag interstitials, grain boundaries, and dislocations are directly correlated to the sintering temperature, and achieve a figure of merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and resolve Ag2Se's challenges are provided, including stoichiometry issues leading to irreproducible performances. This work highlights the potential of RT solution synthesis in expanding the repertoire of high-performance thermoelectric materials for practical applications.","lang":"eng"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1614-6840"],"issn":["1614-6832"]},"publication_status":"epub_ahead","status":"public","article_type":"original","type":"journal_article","_id":"15182","department":[{"_id":"MaIb"},{"_id":"LifeSc"}],"date_updated":"2024-03-25T09:21:05Z","quality_controlled":"1","publisher":"Wiley","oa":1,"acknowledgement":"This work was supported by the Scientific Service Units (SSU) of ISTA through resources provided by the Electron Microscopy Facility (EMF), the Lab Support Facility (LSF), and the Nanofabrication Facility (NNF).

Such catalysts must contain multiple adsorption/reaction sites to cope with the high demands of reversible oxygen electrodes. Herein, we propose a high entropy alloy (HEA) based on relatively abundant elements as a bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays superior OER performance with an overpotential of 265 mV at a current density of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard commercial catalyst based on RuO2. This high performance is partially explained by the presence of twinned defects, the incidence of large lattice distortions, and the electronic synergy between the different components, being Cr key to decreasing the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays superior ORR performance with a half-potential of 0.78 V and an onset potential of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi HEA as air cathode and a zinc foil as the anode. The assembled cells provide an open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8 mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.","lang":"eng"}],"oa_version":"None","scopus_import":"1","intvolume":" 58","month":"04"},{"publication_status":"published","publication_identifier":{"eissn":["1944-8252"],"issn":["1944-8244"]},"language":[{"iso":"eng"}],"file":[{"creator":"dernst","date_updated":"2023-05-30T07:38:44Z","file_size":5640829,"date_created":"2023-05-30T07:38:44Z","file_name":"2023_ACSAppliedMaterials_Nan.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","checksum":"23893be46763c4c78daacddd019de821","file_id":"13099","success":1}],"volume":15,"issue":"19","abstract":[{"lang":"eng","text":"There is a need for the development of lead-free thermoelectric materials for medium-/high-temperature applications.

However, the relatively high material processing cost limits their real applications. Silver selenide (Ag2Se) is one of the very few n-type thermoelectric (TE) materials for room-temperature applications. Herein, we report a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se, which can be extended to other metal chalcogenides. These materials reach TE figures of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide (Bi2S3) particles also prepared in an aqueous solution are incorporated into the Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt % of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering. The presence of Bi2S3 significantly improves the Seebeck coefficient and power factor while at the same time decreasing the thermal conductivity with no apparent drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT value (zTave) of 0.93 in the 300–390 K range is demonstrated.","lang":"eng"}]},{"author":[{"last_name":"Liu","full_name":"Liu, Yu","orcid":"0000-0001-7313-6740","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"first_name":"Mingquan","last_name":"Li","full_name":"Li, Mingquan"},{"last_name":"Wan","full_name":"Wan, Shanhong","first_name":"Shanhong"},{"first_name":"Khak Ho","last_name":"Lim","full_name":"Lim, Khak Ho"},{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"last_name":"Li","full_name":"Li, Mengyao","first_name":"Mengyao"},{"first_name":"Junshan","full_name":"Li, Junshan","last_name":"Li"},{"last_name":"Ibáñez","full_name":"Ibáñez, Maria","orcid":"0000-0001-5013-2843","id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria"},{"last_name":"Hong","full_name":"Hong, Min","first_name":"Min"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"article_processing_charge":"No","external_id":{"isi":["001008564800001"],"pmid":["37310395"]},"title":"Surface chemistry and band engineering in AgSbSe₂: Toward high thermoelectric performance","citation":{"mla":"Liu, Yu, et al. “Surface Chemistry and Band Engineering in AgSbSe₂: Toward High Thermoelectric Performance.” ACS Nano, vol. 17, no. 12, American Chemical Society, 2023, pp. 11923–11934, doi:10.1021/acsnano.3c03541.","ama":"Liu Y, Li M, Wan S, et al.

AgSbSe2 is characterized by relatively low thermal conductivities and high Seebeck coefficients, but its main limitation is moderate electrical conductivity. Herein, we detail an efficient and scalable hot-injection synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier concentration and improve the electrical conductivity, these NCs are doped with Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using a reducing NaBH4 solution to displace the organic ligand and anneal the material under a forming gas flow. The TE properties of the dense materials obtained from the consolidation of the NCs using a hot pressing are then characterized. The presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier concentration and, consequently, the electrical conductivity. Opportunely, the measured Seebeck coefficient varied within a small range upon Sn doping. The excellent performance obtained when Sn2+ ions are prevented from oxidation is rationalized by modeling the system. Calculated band structures disclosed that Sn doping induces convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic effective mass. The dramatically enhanced carrier transport leads to a maximized power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon scattering is significantly enhanced in the NC-based materials, yielding an ultralow thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate for medium-temperature TE applications.","lang":"eng"}],"oa_version":"None","pmid":1},{"_id":"12885","type":"dissertation","status":"public","supervisor":[{"last_name":"Ibáñez","full_name":"Ibáñez, Maria","orcid":"0000-0001-5013-2843","first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2023-08-14T07:25:26Z","ddc":["546","541"],"file_date_updated":"2023-05-02T07:43:18Z","department":[{"_id":"GradSch"},{"_id":"MaIb"}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"abstract":[{"lang":"eng","text":"High-performance semiconductors rely upon precise control of heat and charge transport.

However, precise control over the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid conformational change in the PEDOT:PSS films. In particular, basic amino acid Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment further induces highly orientated lamellar stacking microstructures to increase σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel trigonal-shape thermoelectric device is designed and assembled by the as-prepared PEDOT:PSS films in order to harvest heat via a vertical temperature gradient. An output power density of 33 μW cm−2 is generated at a temperature difference of 40 K, showing the potential application for low-grade wearable electronic devices.","lang":"eng"}],"oa_version":"None","article_processing_charge":"No","external_id":{"isi":["000911497000001"]},"author":[{"first_name":"Li","full_name":"Zhang, Li","last_name":"Zhang"},{"first_name":"Xingyu","last_name":"Liu","full_name":"Liu, Xingyu"},{"first_name":"Ting","full_name":"Wu, Ting","last_name":"Wu"},{"full_name":"Xu, Shengduo","last_name":"Xu","first_name":"Shengduo","id":"12ab8624-4c8a-11ec-9e11-e1ac2438f22f"},{"full_name":"Suo, Guoquan","last_name":"Suo","first_name":"Guoquan"},{"first_name":"Xiaohui","last_name":"Ye","full_name":"Ye, Xiaohui"},{"first_name":"Xiaojiang","last_name":"Hou","full_name":"Hou, Xiaojiang"},{"first_name":"Yanling","last_name":"Yang","full_name":"Yang, Yanling"},{"last_name":"Liu","full_name":"Liu, Qingfeng","first_name":"Qingfeng"},{"first_name":"Hongqiang","full_name":"Wang, Hongqiang","last_name":"Wang"}],"title":"Two-step post-treatment to deliver high performance thermoelectric device with vertical temperature gradient","citation":{"chicago":"Zhang, Li, Xingyu Liu, Ting Wu, Shengduo Xu, Guoquan Suo, Xiaohui Ye, Xiaojiang Hou, Yanling Yang, Qingfeng Liu, and Hongqiang Wang. “Two-Step Post-Treatment to Deliver High Performance Thermoelectric Device with Vertical Temperature Gradient.” Applied Surface Science.

However, traditional doping inevitably deteriorates carrier mobility. Herein, we develop a strategy for fine tuning of defects to improve carrier mobility. To begin, n-type PbTe is created by compensating for the intrinsic Pb vacancy in bare PbTe. Excess Pb2+ reduces vacancy scattering, resulting in a high carrier mobility of ∼3400 cm2 V–1 s–1. Then, excess Ag is introduced to compensate for the remaining intrinsic Pb vacancies. We find that excess Ag exhibits a dynamic doping process with increasing temperatures, increasing both the carrier concentration and carrier mobility throughout a wide temperature range; specifically, an ultrahigh carrier mobility ∼7300 cm2 V–1 s–1 is obtained for Pb1.01Te + 0.002Ag at 300 K. Moreover, the dynamic doping-induced high carrier concentration suppresses the bipolar thermal conductivity at high temperatures. The final step is using iodine to optimize the carrier concentration to ∼1019 cm–3. Ultimately, a maximum ZT value of ∼1.5 and a large average ZTave value of ∼1.0 at 300–773 K are obtained for Pb1.01Te0.998I0.002 + 0.002Ag. These findings demonstrate that fine tuning of defects with <0.5% impurities can remarkably enhance carrier mobility and improve thermoelectric performance.","lang":"eng"}],"intvolume":" 35","month":"01","scopus_import":"1","ddc":["540"],"date_updated":"2023-08-14T12:57:44Z","file_date_updated":"2023-08-14T12:57:25Z","department":[{"_id":"MaIb"}],"_id":"12331","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article"},{"publisher":"American Chemical Society","quality_controlled":"1","acknowledgement":"The authors acknowledge support from the projects ENE2016-77798-C4-3-R and NANOGEN (PID2020-116093RB-C43) funded by MCIN/AEI/10.13039/501100011033/and by “ERDF A way of making Europe”, and by the “European Union”.

In contrast, Cu2–xTe, another member of the copper chalcogenide family, typically exhibits low Seebeck coefficients that limit its potential to achieve a superior thermoelectric figure of merit, zT, particularly in the low-temperature range where this material could be effective. To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering strategy allows for precise adjustment of Cu/Te ratios and results in a reversible phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically confirmed by in situ high-temperature X-ray diffraction combined with differential scanning calorimetry analysis. The phase transition leads to a conversion from metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain growth, minimizing thermal conductivity and decreasing hole concentration.

One prominent example is single-atom alloys, where the reactive dopant atoms can preferentially locate in the bulk or at different sites on the surface of the nanoparticle. However, ab initio modeling of catalysts usually only considers one site of the catalyst, neglecting the effects of multiple sites. Here, nanoparticles of copper doped with single-atom rhodium or palladium are modeled for the dehydrogenation of propane. Single-atom alloy nanoparticles are simulated at 400–600 K, using machine learning potentials trained on density functional theory calculations, and then the occupation of different single-atom active sites is identified using a similarity kernel. Further, the turnover frequency for all possible sites is calculated for propane dehydrogenation to propene through microkinetic modeling using density functional theory calculations. The total turnover frequencies of the whole nanoparticle are then described from both the population and the individual turnover frequency of each site. Under operating conditions, rhodium as a dopant is found to almost exclusively occupy (111) surface sites while palladium as a dopant occupies a greater variety of facets. Undercoordinated dopant surface sites are found to tend to be more reactive for propane dehydrogenation compared to the (111) surface. It is found that considering the dynamics of the single-atom alloy nanoparticle has a profound effect on the calculated catalytic activity of single-atom alloys by several orders of magnitude."}],"pmid":1,"oa_version":"Published Version","author":[{"last_name":"Bunting","orcid":"0000-0001-6928-074X","full_name":"Bunting, Rhys","id":"91deeae8-1207-11ec-b130-c194ad5b50c6","first_name":"Rhys"},{"orcid":"0009-0000-1457-795X","full_name":"Wodaczek, Felix","last_name":"Wodaczek","first_name":"Felix","id":"8b4b6a9f-32b0-11ee-9fa8-bbe85e26258e"},{"last_name":"Torabi","full_name":"Torabi, Tina","first_name":"Tina"},{"first_name":"Bingqing","id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9","orcid":"0000-0002-3584-9632","full_name":"Cheng, Bingqing","last_name":"Cheng"}],"article_processing_charge":"Yes (via OA deal)","external_id":{"isi":["001020623900001"],"pmid":["37390457"]},"title":"Reactivity of single-atom alloy nanoparticles: Modeling the dehydrogenation of propane","citation":{"ama":"Bunting R, Wodaczek F, Torabi T, Cheng B.

However, elusive active centers and reaction mechanism issues inhibit further optimization of its performance. In this work, advanced microkinetic modeling with the adsorbate–adsorbate interaction and nanoparticle size effect based on first-principles calculations is developed. A full mechanism uncovering the significance of adsorbate–adsorbate interaction is determined on Pd nanoparticles. We demonstrate unambiguously that Pd(100) with main coverage species of O2 and H is beneficial to H2O2 production, being consistent with experimental operando observation, while H2O forms on Pd(111) covered by O species and Pd(211) covered by O and OH species. Kinetic analyses further enable quantitative estimation of the influence of temperature, pressure, and particle size. Large-size Pd nanoparticles are found to achieve a high H2O2 reaction rate when the operating conditions are moderate temperature and higher oxygen partial pressure. We reveal that specific facets of the Pd nanoparticles are crucial factors for their selectivity and activity. Consistent with the experiment, the production of H2O2 is discovered to be more favorable on Pd nanoparticles containing Pd(100) facets. The ratio of H2/O2 induces substantial variations in the coverage of intermediates of O2 and H on Pd(100), resulting in a change in product selectivity.","lang":"eng"}],"oa_version":"Published Version","issue":"22","volume":13,"publication_status":"published","publication_identifier":{"eissn":["2155-5435"]},"language":[{"iso":"eng"}],"file":[{"file_name":"2023_ACSCatalysis_.pdf","date_created":"2023-12-11T11:55:09Z","creator":"dernst","file_size":14813812,"date_updated":"2023-12-11T11:55:09Z","success":1,"file_id":"14676","checksum":"a97c771077af71ddfb2249e34530895c","relation":"main_file","access_level":"open_access","content_type":"application/pdf"}],"article_processing_charge":"Yes (in subscription journal)","author":[{"first_name":"Jinyan","last_name":"Zhao","full_name":"Zhao, Jinyan"},{"full_name":"Yao, Zihao","last_name":"Yao","first_name":"Zihao"},{"full_name":"Bunting, Rhys","orcid":"0000-0001-6928-074X","last_name":"Bunting","first_name":"Rhys","id":"91deeae8-1207-11ec-b130-c194ad5b50c6"},{"first_name":"P.","full_name":"Hu, P.","last_name":"Hu"},{"first_name":"Jianguo","full_name":"Wang, Jianguo","last_name":"Wang"}],"title":"Microkinetic modeling with size-dependent and adsorbate-adsorbate interactions for the direct synthesis of H₂O₂ over Pd nanoparticles","citation":{"mla":"Zhao, Jinyan, et al. “Microkinetic Modeling with Size-Dependent and Adsorbate-Adsorbate Interactions for the Direct Synthesis of H₂O₂ over Pd Nanoparticles.” ACS Catalysis, vol. 13, no. 22, American Chemical Society, 2023, pp. 15054–73, doi:10.1021/acscatal.3c03893.","ieee":"J.

To this end, the combination of an electrolyte-gated field-effect transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR) probe serving as gate electrode has been investigated to deconvolute surface mass and charge density variations associated to surface reactions. However, applying an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce gradual morphological changes of the thin gold film, leading to an irreversible blue-shift of the SPR wavelength and a substantial signal drift. We show that mild annealing leads to optical and electronic signal stabilization (20-fold lower signal drift than as-sputtered fiber optic gates) and improved overall analytical performance characteristics. The thermal treatment prevents morphological changes of the thin gold-film occurring during operation, hence providing reliable and stable data immediately upon gate voltage application. Thus, the readout output of both transducing principles, the optical FO-SPR and electronic EG-FET, stays constant throughout the whole sensing time-window and the long-term effect of thermal treatment is also improved, providing stable signals even after 1 year of storage. Annealing should therefore be considered a necessary modification for applying fiber optic gate electrodes in real-time multimodal investigations of surface reactions at the solid-liquid interface.","lang":"eng"}],"month":"07","intvolume":" 11","scopus_import":"1","file":[{"file_name":"2023_FrontiersPhysics_Hasler.pdf","date_created":"2023-08-07T07:48:11Z","creator":"dernst","file_size":2421758,"date_updated":"2023-08-07T07:48:11Z","success":1,"file_id":"13978","checksum":"fb36dda665e57bab006a000bf0faacd5","relation":"main_file","access_level":"open_access","content_type":"application/pdf"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2296-424X"]},"publication_status":"published","volume":11,"_id":"13968","status":"public","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"ddc":["530"],"date_updated":"2023-12-13T12:04:10Z","file_date_updated":"2023-08-07T07:48:11Z","department":[{"_id":"MaIb"}],"acknowledgement":"This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under the Marie Skłodowska-Curie grant agreement No. 813863–BORGES.

Herein, FeCoNiMoW HEA nanoparticles are synthesized using a solution‐based low‐temperature approach. Such FeCoNiMoW nanoparticles show high entropy properties, subtle lattice distortions, and modulated electronic structure, leading to superior OER performance with an overpotential of 233 mV at 10 mA cm−2 and 276 mV at 100 mA cm−2. Density functional theory calculations reveal the electronic structures of the FeCoNiMoW active sites with an optimized d‐band center position that enables suitable adsorption of OOH* intermediates and reduces the Gibbs free energy barrier in the OER process. Aqueous zinc–air batteries (ZABs) based on this HEA demonstrate a high open circuit potential of 1.59 V, a peak power density of 116.9 mW cm−2, a specific capacity of 857 mAh gZn−1, and excellent stability for over 660 h of continuous charge–discharge cycles. Flexible and solid ZABs are also assembled and tested, displaying excellent charge–discharge performance at different bending angles.

However, sluggish ionic transport kinetics and the unstable electrode structure during ionic insertion/extraction hampers their deployment. Herein, we propose a new cathode material based on a layered metal chalcogenide (LMC), bismuth telluride (Bi2Te3), coated with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi2Te3@PPy composite presents strong ionic absorption affinity, high oxidation resistance, and high structural stability. The ZIBs based on Bi2Te3@PPy cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles. They also present outstanding stability even under bending. In addition, we analyze here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron spectroscopy, and computational tools and demonstrate that, in the aqueous system, Zn2+ is not inserted into the cathode as previously assumed. In contrast, proton charge storage dominates the process. Overall, this work not only shows the great potential of LMCs as ZIBs cathode materials and the advantages of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable ZIBs based on LMCs.","lang":"eng"}],"date_created":"2023-10-17T10:53:56Z","date_published":"2023-08-09T00:00:00Z","doi":"10.1002/adma.202305128","publication":"Advanced Materials","language":[{"iso":"eng"}],"day":"09","year":"2023","publication_status":"accepted","isi":1,"publication_identifier":{"issn":["0935-9648"],"eissn":["1521-4095"]},"keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"status":"public","article_type":"original","type":"journal_article","article_number":"2305128","_id":"14435","department":[{"_id":"MaIb"}],"title":"A layered Bi2Te3@PPy cathode for aqueous zinc ion batteries: Mechanism and application in printed flexible batteries","article_processing_charge":"No","external_id":{"pmid":["37555532"],"isi":["001085681000001"]},"author":[{"first_name":"Guifang","last_name":"Zeng","full_name":"Zeng, Guifang"},{"first_name":"Qing","full_name":"Sun, Qing","last_name":"Sun"},{"id":"03a7e858-01b1-11ec-8b71-99ae6c4a05bc","first_name":"Sharona","last_name":"Horta","full_name":"Horta, Sharona"},{"last_name":"Wang","full_name":"Wang, Shang","first_name":"Shang"},{"last_name":"Lu","full_name":"Lu, Xuan","first_name":"Xuan"},{"first_name":"Chaoyue","last_name":"Zhang","full_name":"Zhang, Chaoyue"},{"first_name":"Jing","last_name":"Li","full_name":"Li, Jing"},{"first_name":"Junshan","full_name":"Li, Junshan","last_name":"Li"},{"first_name":"Lijie","full_name":"Ci, Lijie","last_name":"Ci"},{"last_name":"Tian","full_name":"Tian, Yanhong","first_name":"Yanhong"},{"first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Zeng, G., Sun, Q., Horta, S., Wang, S., Lu, X., Zhang, C., … Cabot, A.
