COMPOSITE PHOTOCATALYST PARTICLE, ITS MANUFACTURING METHOD, AND COMPOSITE PHOTOCATALYST FILM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a composite photocatalyst film which is capable of inexpensively and largely obtaining a composite photocatalyst film having high photocatalytic ability.;SOLUTION: The manufacturing method of the composite photocatalyst film is characterized by having a boehmite film formation step of forming boehmite film 2 on the surface of an aluminum member 1 by performing the hydrothermal pressurization treatment of the aluminum member 1 and a treatment step of suspending particles of anatase type titanium dioxide in a potassium permanganate solution, immersing the boehmite film 2 in the suspension solution and performing the hydrothermal pressurization treatment of them.;COPYRIGHT: (C)2008,JPO&INPIT
