Reduced Graphene Oxide-Coated CuFeO with Fenton-like Catalytic Degradation Performance for Terramycin.

A novel Fenton-like catalyst made of reduced graphene oxide-coated CuFeO (rGO-coated CuFeO) was synthesized by the hydrothermal reaction method to remove terramycin from aqueous solutions. The catalytic degradation performance of rGO-coated CuFeO for terramycin was verified with HO activation. The characterization reveals that rGO-coated CuFeO has a micro- and mesoporous structure, with groups such as C=C/C-C, CH-CO, and HO-C=O found on the surface. The Fenton-like catalytic degradation of terramycin by rGO-coated CuFeO was in line with the pseudo-second-order kinetic model, and the elevated temperature accelerated the reaction. Terramycin was catalytically degraded by rGO-coated CuFeO in two steps: terramycin was first adsorbed by rGO, and then Fenton-like degradation took place on its surface. This research presents new insight into the design and fabrication of Fenton-like catalysts with enhanced performance.
