      Selim, Shababa; Pastor , Ernest; García-Tecedor, Miguel; Morris, Madeleine; Francàs Forcada, Laia; Sachs, Michael; Moss, Benjamin; Corby, Sacha; Mesa, Camilo A.; Giménez Juliá, Sixto; Kafizas, Andreas; Bakulin, Artem; Durrant, James American Chemical Society (2019-11-27)
      Oxygen vacancies are ubiquitous in metal oxides and critical to performance, yet the impact of these states upon charge carrier dynamics important for photoelectrochemical and photocatalytic applications remains contentious ...

    • closedAccess   Photoelectrochemical water splitting with dual-photoelectrode tandem and parallel configurations: Enhancing light harvesting and carrier collection efficiencies 

      Keshavarzi, Reza; Mousavian, Mahlasadat; Omrani, MirKazem; Mirkhani, Valiollah; Afzali, Niloufar; Mesa, Camilo A.; Mohammadpoor-Baltork, Iraj; Giménez Juliá, Sixto Elsevier (2023)
      Photoelectrochemical (PEC) water splitting stands out as one of the most promising technologies to store solar energy into chemical bonds and decarbonize industry and transport. In the present study, we develop ...

    • openAccess   Ru-based nanoparticles supported on carbon nanotubes for electrocatalytic hydrogen evolution: structural and electronic effects 

      Romero, Núria; Fenoll, Dídac A.; Gil Jiménez, Laia; Campos Jara, Sergi; Creus, Jordi; Martí Balaguer, Gerard; Heras-Domingo, Javier; Collière, Vincent; Mesa, Camilo A.; Giménez Juliá, Sixto; Francàs Forcada, Laia; Rodriguez-Santiago, Luís; Solans Monfort, Xavier; Sodupe, Mariona; Bofill, Roger; PHILIPPOT, Karine; García-Antón, Jordi; Sala, Xavier Royal Society of Chemistry (2023-10-10)
      The performance of Ru-based nanoparticles (NPs) in the hydrogen evolution reaction (HER) relies on both their structural properties and the oxidation state of the metal. Herein, the versatility of the organometallic approach ...
