TITANIUM OXIDE BASE PHOTOCATALYSTS

摘要

A quaternary oxide includes a dopant metal, a dopant nonmetal, titanium, and oxygen. The atomic ratio of titanium, oxygen and dopant nonmetal may be 1 : 0.5 - 1.99 : 0.01 - 1.5. Quaternary oxides may be used in catalytic compositions, in coatings for disinfecting surfaces and in coatings for self-cleaning surfaces. A method of making a quaternary oxide includes combining ingredients including a titanium source, a dopant nonmetal source, a dopant metal salt, and a polar organic solvent to form a reaction mixture; and heating the reaction mixture.
