Abstract
Disclosed are metal nitride photocatalyst particles and/or metal oxynitride photocatalyst particles having high dispersibility. The metal nitride photocatalyst particles and/or metal oxynitride photocatalyst particles having high dispersibility can be obtained by containing metal nitride photocatalyst particles and/or metal oxynitride photocatalyst particles, which are capable of splitting water under visible light irradiation, and a phosphoric acid polymer that is adsorbed on the surface of the particles. Further, because these particles have high photocatalytic activity under visible light irradiation, splitting water by using these particles can generate hydrogen and/or oxygen with high efficiency.
