Abstract
The application relates to the technical field of water treatment materials, and discloses a preparation method of a bimetal (Bi7.53Co0.47O11.92) catalyst taking MOF as a precursor. A bimetal oxide photocatalyst with oxygen vacancies is obtained by mixing Bi2O3 with excellent visible light response capability with ZIF-67 and then high-temperature calcination, the mutual action between the internal metals can effectively improve the dispersibility of the material and improve the stability of the material. Compared with other photocatalysts, the bimetal oxide catalyst has stronger adsorption and decomposition capacity on pollutants, and the regeneration capacity of the catalytic species can be accelerated through the oxidation and reduction between different valence states of the transition metals in the material. In addition, the bimetal oxide catalyst has good degradation performance on various organic pollutants, and has excellent broad-spectrum antibacterial performance under light conditions.
