--- res: bibo_abstract: - "Branched nanocrystals (NCs) enable high atomic surface exposure within a crystalline network that provides avenues for charge transport. This combination of properties makes branched NCs particularly suitable for a range of applications where both interaction with the media and charge transport are involved. Herein we report on the colloidal synthesis of branched ceria NCs by means of a ligand-mediated overgrowth mechanism. In particular, the differential coverage of oleic acid as an X-type ligand at ceria facets with different atomic density, atomic coordination deficiency, and oxygen vacancy density resulted in a preferential growth in the [111] direction and thus in the formation of ceria octapods. Alcohols, through an esterification alcoholysis reaction, promoted faster growth rates that translated into nanostructures with higher geometrical complexity, increasing the branch aspect ratio and triggering the formation of side branches. On the other hand, the presence of water resulted in a significant reduction of the growth rate, decreasing the reaction yield and eliminating side branching, which we associate to a blocking of the surface reaction sites or a displacement of the alcoholysis reaction. Overall, adjusting the amounts of each chemical, well-defined branched ceria NCs with tuned number, thickness, and length of branches and with overall size ranging from 5 to 45 nm could be produced. We further demonstrate that such branched ceria NCs are able to provide higher surface areas and related oxygen storage capacities (OSC) than quasi-spherical NCs.\r\n\r\n@eng" bibo_authorlist: - foaf_Person: foaf_givenName: Taisiia foaf_name: Berestok, Taisiia foaf_surname: Berestok - foaf_Person: foaf_givenName: Pablo foaf_name: Guardia, Pablo foaf_surname: Guardia - foaf_Person: foaf_givenName: Javier foaf_name: Blanco, Javier foaf_surname: Blanco - foaf_Person: foaf_givenName: Raquel foaf_name: Nafria, Raquel foaf_surname: Nafria - foaf_Person: foaf_givenName: Pau foaf_name: Torruella, Pau foaf_surname: Torruella - foaf_Person: foaf_givenName: Luis foaf_name: López Conesa, Luis foaf_surname: López Conesa - foaf_Person: foaf_givenName: Sònia foaf_name: Estradé, Sònia foaf_surname: Estradé - foaf_Person: foaf_givenName: Maria foaf_name: Ibanez Sabate, Maria foaf_surname: Ibanez Sabate foaf_workInfoHomepage: http://www.librecat.org/personId=43C61214-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-5013-2843 - foaf_Person: foaf_givenName: Jonathan foaf_name: De Roo, Jonathan foaf_surname: De Roo - foaf_Person: foaf_givenName: Zhishan foaf_name: Luo, Zhishan foaf_surname: Luo - foaf_Person: foaf_givenName: Doris foaf_name: Cadavid, Doris foaf_surname: Cadavid - foaf_Person: foaf_givenName: José foaf_name: Martins, José foaf_surname: Martins - foaf_Person: foaf_givenName: Maksym foaf_name: Kovalenko, Maksym foaf_surname: Kovalenko - foaf_Person: foaf_givenName: Francesca foaf_name: Peiró, Francesca foaf_surname: Peiró - foaf_Person: foaf_givenName: Andreu foaf_name: Cabot, Andreu foaf_surname: Cabot bibo_doi: 10.1021/acs.chemmater.7b00896 bibo_issue: '10' bibo_volume: 29 dct_date: 2017^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0897-4756 - http://id.crossref.org/issn/1520-5002 dct_language: eng dct_publisher: American Chemical Society@ dct_title: Tuning branching in ceria nanocrystals@ ...
