Novel ZnS-based photocatalyst and its manufacturing method and hydrogen production method using the same

摘要

The present invention not only shows the activity of the catalyst in visible light, but also the process of producing the photocatalyst is simple and the life of the catalyst obtained is semi-permanent. An object of the present invention is to provide a production method and a method for producing hydrogen using the same.;The catalyst of the present invention is characterized by having the following general formula II.;Pt (a) / Zn [M (b)] S ..... II;(In the above general formula, a represents the weight percentage of Pt in the photocatalyst and has a value of 0.1-3.5, M is one element selected from Co, Fe, Ni, and P, and b represents mol% of M / Zn. Has a value of 0.05-30)
