VISIBLE LIGHT-RESPONSIVE PHOTOCATALYST BODY AND METHOD FOR PRODUCING SAME

摘要

A visible light-responsive photocatalyst body that is obtained by forming a porous titanium oxide coating film, which contains sulfur and has micropores in the surface, on the surface of a titanium or titanium alloy base by performing anodic oxidation on the surface of the base using an electrolytic bath containing sulfur and then subjecting the base after anodic oxidation to a heat treatment. The base has a thickness of 0.005-0.6 mm. The titanium dioxide contained in the titanium oxide coating film has an anatase crystal structure.
