PHOTOCATALYST COMPOSITE PARTICLES AND METHOD FOR PRODUCING SAME

Title:

PHOTOCATALYST COMPOSITE PARTICLES AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2016/067823

Kind Code:

A1

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 are able to be obtained by containing metal nitride photocatalyst particles and/or metal oxynitride photocatalyst particles, which are capable of decomposing water by being irradiated with visible light, and a phosphoric acid polymer that is adsorbed on the surfaces of the particles. Since these particles have high photocatalytic activity under visible light, hydrogen and/or oxygen can be produced with high efficiency through water decomposition that uses these particles.
