▎ 摘　　要

NiFe2O4-reduced graphene oxide (RGO) hybrid materials (NFRGs) were synthesized by a simple one-step combustion method. The structures, morphologies and magnetic properties were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and vibrating sample magnetometer analysis. The results show that graphene oxide sheets are not oxidized, but reduced to RGO. The superparamagnetic behavior of NFRGs was observed. The as-synthesized magnetically separable NFRGs show improved photodegradation performance when compared to neat NiFe2O4, attributed to the narrowing band gap, the efficient transfer of photo-generated electron from NiFe2O4 to RGO sheets, and the improved adsorptive property of photocatalyst due to the high specific surface area of RGO sheets.
