Hematite/reduced graphene oxide (Fe2O3/rGO) nanocomposite was successfully fabricated via a facile solvothermal reaction of iron precursor solution and GO leading to simultaneous deposition of iron oxide nanoparticles and in situ reduction of GO without any reducing agent. Texture and morphology, microstructure, chemical and surface composition of the nanocomposite were investigated by scanning electron microscopy, X-ray diffraction, Raman spectroscopy, thermo-gravimetric analysis and X-ray photoelectron spectroscopy, respectively. Its electrochemical performance as anode material for sodium ion batteries was preliminarily evaluated via galvanostatic cycling. The results prove that the Fe2O3 nanoparticles are uniformly anchored onto the surface of graphene nanosheets and that the Fe2O3/rGO nanocomposite shows interestingly higher specific capacities compared to the bare Fe2O3
