Title:
高活性光触媒の製造方法及び高活性光触媒を用いて低エネルギーで水素ガスを回収する硫化水素の処理方法
Document Type and Number:
Japanese Patent JP4191373
Kind Code:
B2
Abstract:
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.
