摘要

In view of the harm of dye wastewater to the ecological environment and human health and the limitations of traditional treatment technologies, this study focused on the advanced persulfate oxidation technology (PS-AOPs), which synthesized cerium-doped cobalt-based bimetallic organic framework materials (Co/Ce-MOFs-NH₂) by solvothermal method for the activation of pyrosulfate (PMS) for the degradation of rhodamine B (RhB). The rare earth element cerium (Ce) was innovatively introduced to construct a bimetallic synergistic system to solve the problems of single active site and poor cycling stability of monometallic Co-MOFs. The effects of catalyst dosage, PMS concentration, initial pollutant concentration and pH value on the degradation efficiency were systematically explored, and the hydroxyl radicals (·OH). This study provides theoretical support for the design of rare earth element enhanced bimetallic MOFs catalysts.
