Title:
VISIBLE-LIGHT-RESPONSIVE TITANIUM OXIDE MICROPARTICLE DISPERSION, METHOD FOR MANUFACTURING SAME, AND MEMBER HAVING SURFICIAL PHOTOCATALYST THIN FILM FORMED USING SAME DISPERSION
Document Type and Number:
WIPO Patent Application WO/2013/073320
Kind Code:
A1
Abstract:
Provided is a visible-light-responsive titanium oxide microparticle dispersion or the like readily enabling manufacture of a highly transparent photocatalyst thin film demonstrating photocatalyst activity even using visible light alone, and having exceptional titanium oxide microparticle dispersion stability even after storage for prolonged periods of time in cold and dark interior locations. The present invention makes it possible to: produce a peroxotitanic acid solution containing vanadium and a tin compound from a titanium compound, a vanadium compound, a tin compound, a basic substance, hydrogen peroxide, and an aqueous dispersion medium as starting materials; subject the peroxotitanic acid solution to a hydrothermal reaction under high pressure; subsequently admix a copper compound into the acid solution; and obtain a visible-light-responsive titanium oxide microparticle dispersion or the like.
