Progress in Research of New Photocatalyst Response to Visible Light

Since photocatalyst TiO2 research to manufacture success, the scientist carries on the new trial continuously,and succeed to research to manufacture thousands of photocatalysts , and the catalyst efficiency raises continuously. Herein Cu2O by chemical deposition method; electrochemical method;irradiation method polyol process are prepared and Bi2O3 with solid-state reaction ,liquid-state reaction are prepared.
