Yttrium Tantalum Oxynitride Multiphases as Photoanodes for Water Oxidation
Wenping Si, Zahra Pourmand Tehrani, Fatima Haydous +4
Perovskite yttrium tantalum oxynitride is theoretically proposed as a promising semiconductor for solar water splitting because of the predicted bandgap and energy positions of ban…
Suppressed charge recombination in hematite photoanode via protonation and annealing
Wenping Si, Fatima Haydous, Ugljesa Babic +2
Hematite as promising photoanode for solar water splitting suffers from severe bulk and surface charge recombination. This work describes that a protonation-annealing treatment can…
Improved Photoelectrochemical Water Splitting of CaNbO2N Photoanodes by Co-Pi Photodeposition and Surface Passivation
Fatima Haydous, Wenping Si, Vitaliy A. Guzenko +7
Photoelectrochemical solar water splitting is a promising approach to convert solar energy into sustainable hydrogen fuel using semiconductor electrodes. Due to their visible light…
LaTiOxNy thin film model systems for photocatalytic water splitting: physicochemical evolution of the solid-liquid interface and the role of the crystallographic orientation
Markus Pichler, Wenping Si, Fatima Haydous +10
The size of the band gap and the energy position of the band edges make several oxynitride semiconductors promising candidates for efficient hydrogen and oxygen production under so…
