Reduced Graphene Oxide-Coated CuFeO2 with Fenton-like Catalytic Degradation Performance for Terramycin

A novel Fenton-like catalyst made of reduced graphene oxide-coated CuFeO2 (rGO-coated CuFeO2) was synthesized by the hydrothermal reaction method to remove terramycin from aqueous solutions. The catalytic degradation performance of rGO-coated CuFeO2 for terramycin was verified with H2O2 activation....

Description
Summary:A novel Fenton-like catalyst made of reduced graphene oxide-coated CuFeO2 (rGO-coated CuFeO2) was synthesized by the hydrothermal reaction method to remove terramycin from aqueous solutions. The catalytic degradation performance of rGO-coated CuFeO2 for terramycin was verified with H2O2 activation. The characterization reveals that rGO-coated CuFeO2 has a micro- and mesoporous structure, with groups such as C=C/C−C, CH2−CO, and HO−C=O found on the surface. The Fenton-like catalytic degradation of terramycin by rGO-coated CuFeO2 was in line with the pseudo-second-order kinetic model, and the elevated temperature accelerated the reaction. Terramycin was catalytically degraded by rGO-coated CuFeO2 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.
