PHOTOCATALYST-APPLYING AGENT AND METHOD FOR FORMING COATED FILM

摘要

PROBLEM TO BE SOLVED: To provide a means for immobilizing powdery titanium oxide photocatalyst on the surface of a substrate without inhibiting its catalytic activity. SOLUTION: This method for producing the photocatalyst-applying agent is provided by including to obtain a partially dissolved solution by dispersing the titanium oxide photocatalyst powder in a solution containing an alkaline compound and hydrogen peroxide, and partially dissolving the titanium oxide photocatalyst powder. The method for producing the photocatalyst film is provided by applying the photocatalyst-applying agent produced by the above method on a substrate material and drying. COPYRIGHT: (C)2007,JPO&INPIT
