Method for producing high activity photocatalyst, photoactivity catalyst, and method for treating hydrogen sulfide for recovering hydrogen gas under low energy by using high activity photocatalyst
A high activity catalyst is obtained by oxidizing and modifying the surface of zinc sulfide by hydrogen peroxide. An oxidation treatment is carried out in basic aqueous solution. The high activity photocatalyst is added to the basic aqueous solution in which hydrogen sulfide is dissolved to recover hydrogen and sulfur under low energy. Thus, the inexpensive high activity photocatalyst having a high catalytic activity and a long duration of life is realized and hydrogen gas is efficiently generated under little energy.
