Abstract

See full text

A preparation method of photo catalyst by transition metal halide molten salt and use thereof, wherein low-valence titanium complexes stable in air and water are used as a Ti source, transition metal halide is used as molten salt, mixing the Ti source and the molten salt as per a certain mole ratio and grinding, heating at air atmosphere until no lower than a fusion point of the molten salt, keeping the molten salt in a state of melting, maintaining the temperature, washing with water, and reduced TiO2−x rich in Ti3+ and Ov is obtained in one-step melting reaction. Deficiencies that multiple steps are involved for preparing conventional defect titanium dioxide or use of inflammable and explosive reducing gases or other dangerous reducing agents or oxidizing agents have been addressed; and the defect that the Ti source is liable to be dissolved in organic and other solvents is fully avoided.
