Preparation method of porous nano spherical zinc-cadmium sulfide solid solution

The invention discloses a preparation method of a porous nano spherical zinc-cadmium sulfide solid solution and belongs to the technical field of photocatalytic materials. The preparation method comprises the following steps: 1, dissolving Zn(Ac)2.2H2O and Cd(Ac)2.2H2O in a mixed solution of ethylene glycol and sodium hydroxide, and executing stirring vigorously; 2, adding thiourea into the solution prepared in the step 1, continuously stirring them, executing heating for reaction, executing cooling to room temperature after the reaction is finished to obtain a crude product, repeatedly washing the crude product with deionized water and absolute ethyl alcohol respectively, centrifugally recovering the product, and carrying out vacuum drying to obtain the porous nano spherical zinc-cadmiumsulfide solid solution. The preparation method is simple, a preparation period is short, the technological process is easy to control, and the porous nano spherical Zn0.5Cd0.5S solid solution materialprepared by the method ha
