The present work is aimed at studying the synergistic catalysis of the bimetal ZIFs containing Co and Znmetal ions prepared by solvothermal method in the degradation of organic pollutants under ambientconditions. The bimetal mixed ZIFs were further characterized by some techniques such as XRD, SEM,TG-DTG, XPS, UV–vis, ESR, and N2-adsorption. Interestingly, the sample prepared with equal metal ions(1Zn:1Co) showed the highest catalytic performance for methylene blue (MB) degradation (94.10 %). Thismay be associated with the interaction between cobalt and zinc within the adjacent lattice, which makethe MB molecule to be easily adsorbed and degraded on empty electron orbit. Furthermore, the highestdegradation of MB was achieved with 98.83 % under the optimized conditions (catalyst weight of 50 mg,pH of 5, 3 h, 30 C). Besides, the various substrates such as methyl orange, indole, rofloxacin, methyl blue,and tetracycline were also investigated under the same conditions. Additionally, the DFT calculationresults suggested the more orbital distribution (LUMO, HOMO) of ZIF(1Zn:1Co) can result to more electronsbeing easily captured, and generate more radicals via electron transfer. Finally, the photocatalyticdegradation of MB is consistent with the first law of kinetics, and the activation energy is 26.797 KJ/molin the presence of ZIF(1Zn:1Co).
