Title:
VISIBLE LIGHT RESPONSIVE PHOTOCATALYST MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/203996
Kind Code:
A1
Abstract:
Disclosed is a visible light responsive photocatalyst material formed by covering a base material with photocatalyst particles achieving both high crystallinity and micronization of primary particles and capable of producing hydrogen. This photocatalyst material is a visible responsive photocatalyst material formed by immobilizing, on a base material, a photocatalyst layer including photocatalyst particles that are each capable of producing hydrogen and have a primary particle diameter of 100 nm or less. More preferably, a pore having 10-200 nm inclusive is formed between the photocatalyst particles. Consequently, the appearance of water splitting due to high photocatalytic activity under visible light irradiation becomes possible.
