Photocatalyst comprising titanium fluoride nitride for water decomposition with visible light irradiation

摘要

A photo-catalyst containing titanium fluoride nitride comprising, Ti(IV)O_aN_bF_c or a compound represented by MeTi(IV)O_aN_bF_c prepared by doping at least one metal Me selected from the group consisting of alkali or alkaline earth metals on Ti(IV)O_aN_bF_c. (wherein, b is 0.1 to 1, c is 0.1 to 1 and a is a value to maintain Ti(IV) and is decided in relation to b and c.). The photo-catalyst containing titanium fluoride nitride is especially characterized by loading at least one promoter selected from the group consisting of Pt, Ni and Pd.
