| titleOfInvention | A kind of zinc-copper sulfide photocatalyst for treating printing and dyeing wastewater and preparation method thereof |
| abstract | The invention belongs to the technical field of printing and dyeing wastewater treatment, and provides a zinc-copper sulfide photocatalyst for treating printing and dyeing wastewater and a preparation method. In the method, copper chloride, zinc acetate and thiourea are used as raw materials, ethylene glycol is used as solvent, sodium dodecylbenzene sulfonate is used as surfactant, and terephthalic acid is used as cosurfactant to prepare zinc copper sulfide The flower-shaped nanometer hollow spheres are then compounded with the yellow tungstic acid generated in situ, and further calcined to obtain a tungsten trioxide-doped zinc-copper sulfide photocatalyst. Compared with the traditional method, the photocatalyst prepared by the present invention can inhibit the recombination of photogenerated electron and hole pairs generated under light excitation, improve the separation efficiency of photogenerated carriers, and further improve the activity and catalytic efficiency of the photocatalyst. |
