Photocatalysts for overall water splitting have great potential in solar energy applications. A variety of photocatalysts have shown activity for water splitting. In particular, oxysulfides are the great interest because of their ability to generate H_2 and O_2 from water under visible light. However, they are generally synthesized under H_2S flow, which is an extremely harmful gas for humans. In this study, La_2O_2S_2 was synthesized at low temperature without H_2S gas, and its photocatalytic activity was confirmed by hydrogen generation experiments.
