Document Type and Number:
Japanese Patent JP2004041905
Kind Code:
A
Abstract:
To provide a photocatalyst body high in activity by reoughnening the reaction surface of a photocatalyst.
An inorganic fiber paper immersed in an impregnation liquid which contains anatase type titanium oxide, rutile type titanium oxide, a silica sol and polyvinyl alcohol, is wound around a mold to be molded into a cylindrical shape. After the molded one is dried, it is baked to manufacture the photocatalyst body. By this method, the photocatalyst body, of which the fiber directions are not constant and the surface has many recessed and protruded parts, can be formed and the reaction surface of the photocatalyst is roughened.
