Bimetal cobalt-Iron based organic frameworks with coordinated sites as synergistic catalyst for fenton catalysis study and antibacterial efficiency

Fenton-like catalysis has found a broad application for the removal of drug compounds from wastewater. Herein, we presented a synthesis method for the novel coordinatively unsaturated cobalt-iron bimetallic based metal-organic frameworks as heterogeneous catalysts for Fenton-like catalysis in amoxicillin (AMX) degradation process under the presence of H2O2. In order to optimize the process, the influences of catalyst dosages, H2O2 concentrations, initial pH, and the coexisting anions on AMX degradation were studied. Results showed that the complete AMX degradation was found at pH: 7, H2O2: 3 mM, catalyst dose: 0.1 g/L. After five cycle times, coordinatively unsaturated cobalt-iron bimetallic based metal-organic frameworks can still perform substantial Fenton-catalytic activity (100.0 % within 30 min). This project highlights the synthesized catalyst with outstanding performances for Fenton catalytic degradation of drug compounds. The cobalt-iron based organic frameworks with coordinated sites indicated significant antibacterial performance in the disc diffusion analysis.
