PROBLEM TO BE SOLVED: To provide a method of producing a photocatalyst of a nonmetallic-element-doped titanium oxide having the common performance of titanium oxide of decomposing oxidatively organic matter adsorbed on the surface by absorbing UV light which performance is modified so as to also respond to visible light.SOLUTION: The method of manufacturing the titanium oxide photocatalyst comprises mixing a compound of formula TiX (wherein, X is at least one nonmetallic element selected from P, N, Sand C) with a titanium compound in a solvent and heating and crystallizing the mixture to obtain the titanium oxide photocatalyst and enables uniform doping of nonmetallic elements in the resultant titanium oxide photocatalyst. The titanium oxide photocatalyst obtained by the method can respond not only to UV light but to visible light. |
