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: m(a)/Cd x Zn y M z S VII wherein 'm' represents at least one doped metal element as an electron acceptor selected from the group consisting of Ni, Pt, Ru or 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, Ti, Mn, Fe, Pd, Pt, P, Cu, Ag, Ir, Sb, Pb, Ga and Re. 'z' represents an atom % of M/(Cd+Zn+M), ranging from 0.05 to 20.00 and 'x'and 'y' represent an atom % of Cd/(Cd+Zn+M) and an atom % of Zn/(Cd+Zn+M), ranging from 10.00 to 90.00, respectively. Photocatalysts in accordance with the present invention have advantages of having high degree of photocatalytic activities in visible light for CdS photocatalysts and in uv light for ZnS photocatalysts, respectively. Thereby, wide ranges of light sources are available in the present invention. Also, it is found that photocatalysts of present invention overcome limited activities to the reductants in the photo reaction and have a much longer lifetime and an increased hydrogen production rate.
