Research Abstract |
Photocatalytic water splitting is a promising technology for the sustainable production of hydrogen gas as an energy carrier. The utilization of metal or metal-oxide particle cocatalysts to semiconductor photocatalysts greatly enhances the overall photecatalytic efficiency. In this study, the electronic structure of cocatalyst on the semiconductor photocatalyst under UV irradiation was investigated by the in-situ X-ray absorption spectroscopy.
