A preparation method of cobalt-doped porous ZnO for pollutant adsorption, comprising the following steps: (1) mixing zinc acetate, cobalt acetate and ammonium bicarbonate to obtain a basic zinc-cobalt carbonate compound, and drying; (2) mixing zinc acetate, cobalt acetate and ammonium bicarbonate The mixture obtained in step (1) is calcined to obtain a cobalt-doped porous zinc oxide composite material. This method utilizes the direct precipitation method to dope the transition metal cobalt in the ZnO lattice to prepare cobalt-doped ZnO composite porous nanosheets, which improves the adsorption performance of pure ZnO and expands the light absorption of ZnO scope. The material can be used for the purification, adsorption and photocatalytic degradation of dye sewage, and the material synthesis method is green, simple, and low in cost, and is a process that can be manufactured and applied on a large scale. |
