<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a photocatalyst material which is capable of efficiently manufacturing a photocatalyst material with high activities without effecting complicated steps. <P>SOLUTION: In the manufacturing method of the photocatalyst material by supporting the photocatalyst and a metal to a ceramic porous material, it comprises attaching the photocatalyst sol to the ceramic porous material, then drying the resultant and attaching a metal colloid liquid, then drying and calcining the same. The method can increase the production efficiency because the production steps are greatly simplified in comparison with the conventional methods by conducting the formation of the photocatalyst thin film to the ceramic porous material and the decomposition removal of the organic matter in the metal colloid liquid with the calcination step at one time. Thus, the photocatalyst material with high activities can be obtained by completely eliminating the organic matter of the metal colloid liquid through conducting the calcination at elevated temperature. <P>COPYRIGHT: (C)2007,JPO&INPIT |
