Preparation and Electrochemical Performance of TiO<sub>2</sub>-NTs/rGO Composite
The precursor of titanium dioxide nanotubes(TiO<sub>2</sub>-NTs) was obtained by alkaline hydrothermal approach, which was supported by graphene oxide to form titanium dioxide nanotubes/reduced graphene oxide composite(TiO<sub>2</sub>-NTs/rGO). The composite was characterized...

| description | The precursor of titanium dioxide nanotubes(TiO<sub>2</sub>-NTs) was obtained by alkaline hydrothermal approach, which was supported by graphene oxide to form titanium dioxide nanotubes/reduced graphene oxide composite(TiO<sub>2</sub>-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 TiO<sub>2</sub>-NTs in composite is TiO<sub>2</sub>(B) with diameter of about 25-30nm. Compared with pure TiO<sub>2</sub>-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 TiO<sub>2</sub>-NTs/rGO and TiO<sub>2</sub>-NTs are 258.5mAh/g and 214.9mAh/g, respectively. The charge transfer resistance of composite is smaller than pure TiO<sub>2</sub>-NTs characterized by electrochemical impedance spectroscopy. |
