    • openAccess   Electronic Effects Determine the Selectivity of Planar Au–Cu Bimetallic Thin Films for Electrochemical CO2 Reduction 

      Liu, Kai; Ma, Ming; Wu, Longfei; Valenti, Marco; Cardenas-Morcoso, Drialys; Hofmann, Jan Philipp; Bisquert, Juan; Gimenez, Sixto; Smith, Wilson A. American Chemical Society (2019-04-10)
      Au–Cu bimetallic thin films with controlled composition were fabricated by magnetron sputtering co-deposition, and their performance for the electrocatalytic reduction of CO2 was investigated. The uniform planar morphology ...

    • openAccess   Improving the Back Surface Field on an Amorphous Silicon Carbide Thin‐Film Photocathode for Solar Water Splitting 

      Perez-Rodriguez, Paula; Cardenas-Morcoso, Drialys; Digdaya, Ibadillah; Mangel Raventos, Andrea; Procel, Paul; Isabella, Olindo; Gimenez, Sixto; Zeman, Miro; Smith, Wilson A.; Smets, Arno H. M. Wiley-VCH Verlag (2018-06-11)
      Amorphous silicon carbide (a‐SiC:H) is a promising material for photoelectrochemical water splitting owing to its relatively small band‐gap energy and high chemical and optoelectrical stability. This work studies the ...

    • openAccess   Interfacial band-edge energetics for solar fuels production 

      Smith, Wilson A.; Sharp, Ian D.; Strandwitzd, Nicholas C.; Bisquert, Juan Royal Society of Chemistry (2015)
      Photoelectrochemical (PEC) water splitting has received growing attention as a potential pathway to replace fossil fuels and produce a clean, renewable, and sustainable source of fuel. To achieve overall water splitting ...

    • openAccess   Near-complete suppression of surface losses and total internal quantum efficiency in BiVO4 photoanodes 

      Trzesniewski, Bartek J.; Digdaya, Ibadillah; Nagaki, Tetsuro; Ravishankar, Sandheep; Herraiz Cardona, Isaac; Vermaas, David; Longo, Alessandro; Gimenez, Sixto; Smith, Wilson A. Royal Society of Chemistry (2017-05-26)
      Bismuth vanadate (BiVO4) is one of the most efficient light absorbing metal oxides for solar water splitting. BiVO4 photoanodes immersed in an electrolyte in an open circuit configuration and exposed to simulated solar ...

    • openAccess   Suppressing H2 Evolution and Promoting Selective CO2 Electroreduction to CO at Low Overpotentials by Alloying Au with Pd
