NOVEL ZnS PHOTOCATALYST, PREPARATION THEREFOR AND METHOD FOR PRODUCING HYDROGEN BY USE OF THE SAME

摘要

A photocatalyst, represented by formula (II): Pt(a)/Zn[M(b)]S, wherein character "a" represents a percentage by weight of Pt in the photocatalyst, ranging from 0.1 to 3.5; character "M" is an element selected from the group consisting of Co, Fe, Ni and P; character "b" represents a mole % of M/Zn, ranging from 0.05 to 30. It can be active in the range of the visible light, live a semi-permanent life and produce hydrogen at a high yield without using any oxygen-containing organic compound as a hydrogen-producing promotor.
