Abstract A one-pot process for preparing Fe3O4/r-GO-CNTs composites has been realized. In the solvethermal process, benzyl alcohol was used as the solvent and reducing agent. The morphology and structure of the composites were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM). The results demonstrated that the reduction of graphene oxide and the deposition of Fe3O4 about 10 nm on r-GO-CNTs surface were occurred simultaneously. The cycling stability of the obtained hybrid is better than that of the pure Fe3O4 electrode material. At the current density of 0.1 A/g, after 100 cycles, its reversible discharge capacity still remained 840 mA·h/g.
