PHOTOCATALYST AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst which is produced in a simple production process and at a low cost and has high photocatalytic activity in a visible light region, and to provide a production method of the photocatalyst. SOLUTION: The photocatalyst comprises titanium oxide and nitrogen having doped nitrogen. In the production method, the photocatalyst comprising titanium oxide and nitrogen having doped nitrogen is prepared by subjecting magnesium and nitrogen to the thermit reaction.
