PHOTOCATALYST SUPPORTING BODY AND METHOD OF MANUFACTURING POROUS BASE MATERIAL FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a material which is more hardly damaged for a porous base material of a photocatalyst supporting body. SOLUTION: The photocatalyst supporting body is constituted by coating the porous ceramic base material with a photoreactive semiconductor mainly composed of titanium oxide and firing the film formed by drying and solidifying the coating thereby forming a microporous film. The porous ceramic base material described above is constructed by forming an aluminous film on a porous silicon carbide skeleton body.
