▎ 摘  要

Graphene anchored with nanocrystal Fe2O3 was synthesized by a two-step solvothermal route. The nanocomposite was characterized by X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), scanning electron spectroscopy (SEM) and transmission electron microscopy (TEM). It was found that the Fe2O3 nano-particles were formed and homogeneously anchored on graphene sheets. The electrochemical properties of the nanocomposite were investigated by galvanostatic cycling. The results showed that the Fe2O3/graphere nanocomposite exhibits obviously improved electrochemical properties compared to bare Fe2O3 because of the buffering, confining and conducting effects of the introduced grapheme.
