Hydrogen (H2) production using visible-light photocatalysis for water splitting has attracted considerable attention owing to the growing demand for environmentally friendly and sustainable energy sources. This presentation will demonstrate our previous study on H2 production under visible light irradiation (400–690 nm) with the multicomponent sulfide photocatalyst (Ru/(CuAg)0.15In0.3Zn1.4S2). In this study,we examined the kinetics of photocatalytic generation of H2, stability and reusability of the catalyst over multiple cycles of H2 production and catalyst regeneration.The results will help facilitate a search of stable and efficient photocatalysts for water splitting, and this presentation will reveal fundamental insight into the development of novel visible light-adsorbing photocatalysts.
