CDS PHOTOCATALYST FOR HYDROGEN PRODUCTION, PREPARATION THEREFOR AND METHOD FOR PRODUCING HYDROGEN BY USE OF THE SAME

摘要

The present invention relates to a novel CdS photocatalyst for producinghydrogen from water by photoreaction and preparation therefor, and method forproducing hydrogen by using of the CdS photocatalyst. The CdS photocatalyst ischaracterized by the following general formula V:m(A)/Cd[M(B)]S Vwherein m represents a doped metal element as an electron acceptor, such asPt,Ru, Ir, Co, Rh, Cu, Pd, Ni, or the oxidized compound of one of these metals; Arepresents a percentage by weight of m, ranging from 0.10 to 2.50; M iscatalystelement, e.g. V, Cr, Al and P; and B represents a mole % of M/(M+Cd), rangingfrom0.05 to 20.00.
