▎ 摘　　要

A facile low-temperature approach was employed to prepare CuFe2O4 nanoparticles over chemically reduced graphene oxide (CuFe2O4/rGO) by co-precipitation of rGO with copper and iron salts in one-pot. The structures, compositions, purities, and morphologies of CuFe2O4/rGO composites were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques. The results showed that CuFe2O4 nanoparticles decorated uniformly the rGO sheets. The prepared CuFe2O4/rGO composites were applied as heterogeneous Fenton-like catalysts for the degradation of phenol, as a model pollutant, using high-performance liquid chromatography (HPLC). The photocatalytic activity of the CuFe2O4/rGO composites was also investigated. Complete removal of phenol was achieved within 15 min under photocatalytic conditions at room temperature. The CuFe2O4/rGO nanocomposites exhibited a higher catalytic activity compared to bare CuFe2O4 nanoparticles. The catalytic performance of CuFe2O4/rGO was also higher than TiO2 catalysts.
