▎ 摘　　要

MnFe2O4 nanoparticles grown on graphene were prepared by a facile one-step solution-phase route. The reduction of GO by this method is effective, which was confirmed by X-ray diffraction, Fourier transform infrared, Raman spectroscopy and X-ray photoelectron spectroscopy. The morphology and electromagnetic wave absorption properties of MnFe2O4/GN were also investigated. The as-synthesized MnFe2O4/GN nanocomposites show excellent microwave absorbability. The minimum reflection can reach -31.3 dB at 11.5 GHz with a thickness of 2 mm. The one-pot method we utilized is simple and versatility and the as-synthesized MnFe2O4/GN nanocomposites can be applied in other fields.
