METHOD FOR PRODUCING NOBLE METAL-SUPPORTED PHOTOCATALYST PARTICLES

摘要

PURPOSE: A producing method of noble metal deposited photocatalyst particle, and a producing method of a photocatalyst particle dispersion solution are provided to deposit noble metal with the high efficiency, and to improve the photocatalytic activity of a photocatalyst. CONSTITUTION: A producing method of noble metal deposited photocatalyst particle comprises the following steps: injecting inert gas to a material solution containing a photocatalyst particle and a noble metal precursor; and depositing noble metals on the surface of the photocatalyst particle by irradiating light to the material solution. The photocatalyst particle is a tungsten oxide particle.
