• openAccess   2D Bismuthene as a Functional Interlayer between BiVO4 and NiFeOOH for Enhanced Oxygen-Evolution Photoanodes 

      Cui, Junyi; Daboczi, Matyas; Regue, Miriam; Chin, Yi-Chun; Pagano, Katia; Zhang, Jifang; Isaacs, Mark; Kerherve, Gwilherm; Mornto, Aris; West, James; Gimenez, Sixto; Kim, Ji-Seon; Eslava, Salvador Wiley (2022-10-26)
      BiVO4 has attracted wide attention for oxygen-evolution photoanodes in water-splitting photoelectrochemical devices. However, its performance is hampered by electron-hole recombination at surface states. Herein, partially ...
    • openAccess   Direct Observation of the Chemical Transformations in BiVO4 Photoanodes upon Prolonged Light-Aging Treatments 

      Arcas, Ramón; Cardenas-Morcoso, Drialys; Spadaro, Maria Chiara; García-Tecedor, Miguel; Mesa, Camilo A.; Arbiol, Jordi; Fabregat-Santiago, Francisco; Gimenez, Sixto; Mas, Elena Wiley (2022-03-11)
      Exposing BiVO4 photoanodes to light-aging treatments is known to produce a significant photocurrent enhancement. Until now, the interpretation given to this phenomenon is associated to the formation of oxygen vacancies and ...
