CdZnMS photocatalyst including cations for water decomposition and preparation thereof and method for producing hydrogen by use of the same

摘要

Present invention relates to a CdZnMS photocatalyst for producing hydrogen from water and a method for preparing thereof and a method for producing hydrogen by using said photocatalyst. Said photocatalyst is characterized by the following general formula VII:; ;wherein m represents at least one doped metal element as an electron acceptor selected from the group consisting of Ni, Pt, Ru and the oxidized compound of these metals; a represents a % by weight of m, ranging from 0.10 to 5.00; M is a catalyst element selected from the group consisting of Mo, V, Al, Cs, Mn, Fe, Pd, Pt, P, Cu, Ag, Ir, Sb, Pb, Ga and Re. z represents an atom % of M/(CdZnM), ranging from 0.05 to 20.00 and x and y represent an atom % of Cd/(CdZnM) and an atom % of Zn/(CdZnM), ranging from 10.00 to 90.00, respectively.
