Abstract

To provide a method for preparing a visible light-responsive photocatalyst and a visible light-responsive photocatalyst intermediate, a usage of a visible light-responsive photocatalyst, and the visible light-responsive photocatalyst, the method enabling arbitrary setting of the amount of solvent, thus making it possible to prepare composite fine particles of gold colloids and titanium oxide fine particles in high yield. A method for preparing a visible light-responsive photocatalyst or a visible light-responsive photocatalyst intermediate includes the step of forming a disperse system including an oil liquid containing an organic titanium complex as a dispersant, and an aqueous dispersion containing gold colloids as a dispersoid, and the visible light-responsive photocatalyst or the visible light-responsive photocatalyst intermediate enables the organic titanium complex to undergo hydrolysis to cause clathration of gold colloids, thus forming a clathrate.
