    • 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 ...

    • openAccess   Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells 

      Alvarez, Agustin; Arcas, Ramón; Aranda Alonso, Clara; Bethencourt, Loengrid; Mas, Elena; Saliba, Michael; Fabregat-Santiago, Francisco American Chemical Society (2020-10-01)
      Negative capacitance in the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, which origin is still under discussion. Here we use impedance spectroscopy to analyze these responses ...

    • openAccess   Pencil graphite rods decorated with nickel and nickel-iron as low-cost oxygen evolution reaction electrodes 

      Arcas, Ramón; Koshino, Yuuki; Mas, Elena; Tsuji, Ryuki; Masutani, Hideaki; Miura-Fujiwara, Eri; Haruyama, Yuichi; Nakashima, Seiji; Ito, Seigo; Fabregat-Santiago, Francisco Royal Society of Chemistry (2021)
      Society is demanding clean energy to substitute greatly polluting carbon-based fuels. As an alternative, the use of green hydrogen produced by electrocatalysis constitutes a nice strategy as its products and reactants are ...

    • openAccess   Revealing the contribution of singlet oxygen in the photoelectrochemical oxidation of benzyl alcohol 

      Arcas, Ramón; Peris, Eduardo; Mas, Elena; Fabregat-Santiago, Francisco Royal Society of Chemistry (2021-02)
      Photoelectrochemical approaches are finding use in the transformation of organic molecules beyond water oxidation and CO2 reduction. Among the different reactions that can be performed, the selective oxidation of alcohols ...
