PROBLEM TO BE SOLVED: To improve general performance of titanium oxide, in which ultraviolet light is absorbed and the organic matter adsorbed on the surface thereof is decomposed oxidatively. SOLUTION: Photocatalysts having excellent photocatalytic functions are searched. As a result, the photocatalytic titanium oxide, which is synthesized by mixing a TiX (wherein X is a nonmetallic element such as P, N, S<SB>2</SB>and C) compound with a titanium oxide precursor and heating/crystallizing the obtained mixture, can respond to not only ultraviolet light but also visible light. In particular, it is uncommon in the world for the phosphorus compound-doped photocatalytic titanium oxide to respond to visible light. COPYRIGHT: (C)2009,JPO&INPIT
