▎ 摘  要

AMIL-100(Fe)/graphene oxide (GO) compositewas prepared by a one-step hydrothermalmethod and utilized as a heterogeneous Fenton-like catalyst for methyl orange (MO) degradation. The obtained catalyst was characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), nitrogen adsorption-desorption isotherms, thermogravimetric (TG) analysis, X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR). The effects of H2O2 dosage, initial pH and catalyst dosage on the degradation of MO were investigated. The MIL-100(Fe)/GO presented high catalytic activity for the degradation of MO, achieving almost complete decomposition of MO after 240 min with reaction conditions of 8 mM H2O2, pH of 3.0 and 0.5 g L-1 catalyst. Kinetics analysis showed that MO removal followed a pseudo-first-order kinetic model. The catalyst showed stable catalytic activity and reusability after three successive runs. The possible catalytic mechanism of MIL-100(Fe)/GO was also proposed.
