Title:
TITANIUM OXIDE PARTICLES, DISPERSION LIQUID OF SAME, PHOTOCATALYST THIN FILM, MEMBER HAVING PHOTOCATALYST THIN FILM ON SURFACE, AND METHOD FOR PRODUCING DISPERSION LIQUID OF TITANIUM OXIDE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/059512
Kind Code:
A1
Abstract:
The present invention provides: titanium oxide particles that have higher photocatalytic activity, especially higher photocatalytic activity under visible light than ever before; a dispersion liquid of the titanium oxide particles; a photocatalyst thin film which is formed using this dispersion liquid; a member which has a photocatalyst thin film on the surface; and a method for producing a dispersion liquid of titanium oxide particles. Titanium oxide particles wherein: (1) a tin component and a transition metal component that enhances photocatalytic activity under visible light are solid-solved therein; and (2) an iron component, a titanium component and a silicon component are adhering to the surfaces. A dispersion liquid of titanium oxide particles obtained by dispersing the titanium oxide particles in an aqueous dispersion medium.
