TITANIUM OXYSULFATE AND METHOD FOR PRODUCING TITANIUM DIOXIDE BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing titanium dioxide which exhibits high photocatalytic activity when irradiated with visible light and to provide an inorganic titanium compound as a starting material for producing the titanium dioxide. SOLUTION: Solid titanium oxysulfate whose crystal structure is amorphous is reacted with a nitrogen-containing base and the resulting product is fired.
