The invention relates to a solid solution catalyst with simple substances nickel and cobalt loaded surface and for photocatalytic decomposition of water to produce hydrogen, and a preparation method thereof, and belongs to the technical field of photocatalysts. The preparation method of the catalyst for high-efficiency photocatalytic decomposition of water to produce hydrogen comprises the following steps: dissolving copper acetate and zinc acetate in deionized water, adding sodium sulfide to form a solid solution precursor, adding the obtained precursor to a reaction kettle, reacting at a certain temperature for a period of time, washing the obtained product, and drying to obtain a product zinc cadmium sulfide; and loading metals nickel and cobalt on the surface of the zinc cadmium sulfide. The catalyst improves the reaction rate of hydrogen production through photocatalytic decomposition of water to 211417[mu]mol h<-1>g<-1> from 78130[mu]mol h<-1>g<-1> of pure zinc cadmium sulfide, and improves the performances above 2 times. The catalyst has industrial application in energy crisis solution, and is a new technical means for producing environmentally-friendly novel energy.
