METHOD FOR PRODUCING TITANIUM OXIDE COMPOUND, METHOD FOR PRODUCING ACTIVE METAL-SUPPORTING TITANIUM OXIDE COMPOUND, AND METHOD FOR PRODUCING FINE PARTICLE OF THE ACTIVE METAL-SUPPORTING TITANIUM OXIDE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a method for easily producing a titanium oxide compound excellent in the sterilization rate and the decomposition rate of a harmful gas when it is used as a photocatalyst under irradiation with visible light.

SOLUTION: The method for producing a titanium oxide compound is a method for producing an iron oxide and a sulfur atom- or nitrogen atom-containing titanium oxide compound. The method for producing a titanium oxide compound includes preparing a raw material titanium oxide by reacting a titanium salt and an alkali compound or hydrolyzing a titanium salt, then mixing the raw material titanium oxide, an iron compound and a sulfur compound or a nitrogen compound, and firing the resulting mixture to obtain the iron oxide and the sulfur atom- or nitrogen atom-containing titanium oxide compound.
