摘要：
The precursor of titanium dioxide nanotubes(TiO2-NTs) was obtained by alkaline hydrothermal approach, which was supported by graphene oxide to form titanium dioxide nanotubes/reduced graphene oxide composite(TiO2-NTs/rGO). The composite was characterized by X-ray diffraction(XRD), transmission electron microscope (TEM) and electrochemical measurements. The results show that the crystalline phase of TiO2-NTs in composite is TiO2(B) with diameter of about 25-30nm. Compared with pure TiO2-NTs, the rate performance and cycle life of composite are improved remarkablely by loading on graphene. When discharged at the rate of 1C(335mA/g), the initial discharge capacity of TiO2-NTs/rGO and TiO2-NTs are 258.5mAh/g and 214.9mAh/g, respectively. The charge transfer resistance of composite is smaller than pure TiO2-NTs characterized by electrochemical impedance spectroscopy. © 2017, Journal of Materials Engineering. All right reserved.
