• closedAccess   Plasmonic versus catalytic effect of gold nanoparticles on mesoporous TiO2 electrodes for water splitting 

      Haro, Marta; Abargues, Rafael; Herraiz Cardona, Isaac; Martínez-Pastor, Juan P.; Gimenez, Sixto Elsevier (2014-10)
      Solar water splitting with metal oxide semiconductors constitutes a promising approach to the conversion of solar energy into chemical energy stored in the atomic bonds of hydrogen molecules. In the present study, we ...
    • openAccess   The Complex Role of Carbon Nitride as a Sensitizer in Photoelectrochemical Cells 

      Herraiz Cardona, Isaac; Yang, Xiaofei; Gimenez, Sixto; Antonietti, Markus; Shalom, Menny; Xu, Jingsan Wiley (2015-08)
      The role of carbon nitride (C3N4) as an absorber in a photoelectrochemical cell is reported. C3N4-sensitized TiO2 mesoporous film created via in-situ, vapor-transport growth results in a direct Ti–O–C bonding. The material ...
