Title:
TITANIUM OXIDE FINE PARTICLES, DISPERSION THEREOF, AND METHOD FOR PRODUCING DISPERSION
Document Type and Number:
Japanese Patent JP2020142936
Kind Code:
A
Abstract:
To provide titanium oxide fine particles capable of improving the photocatalytic activity of a photocatalyst by mixing with the photocatalyst.SOLUTION: The present invention provides: titanium oxide fine particles in which at least an iron component and a silicon component are solid-solved, wherein the content of each of the iron component and silicon component is 1-1000 by molar ratio (Ti/Fe or Ti/Si) with titanium; and a titanium oxide fine particle dispersion in which the titanium oxide fine particles are dispersed in an aqueous dispersion medium.SELECTED DRAWING: None
