Composition of titanium oxide particle, dispersion liquid, photocatalyst thin film, photocatalyst thin film having surface and method for producing titanium oxide particle dispersion

摘要

Problem to be solved: to provide a titanium oxide particle having a high photocatalytic activity, a dispersion catalyst, a photocatalyst thin film formed using a dispersion solution, a member having a photocatalytic thin film on the surface, and a method of manufacturing a titanium oxide particle dispersion.SolutionTitanium oxide particles having iron and silicon components attached to the surface, titanium oxide particles having a molar ratio (Ti / Fe) of 10 to 10000, and a molar ratio (Ti / Si) of titanium to silicon in the range of 1 toTitanium oxide particle dispersion in which the titanium oxide particles are dispersed in the aqueous dispersion medium.No selection
