| 英文摘要 | A novel mesoporous-nanotube hybrid composite, namely mesoporous tin dioxide (sno2) overlaying on the surface of multi-walled carbon nanotubes (mwcnts), was prepared by a simple method that included in situ growth of mesoporous sno2 on the surface of mwcnts through hydrothermal method utilizing cetyltrimethylammonium bromide (ctab) as structure-directing agents. nitrogen adsorption-desorption, x-ray diffraction and transmission electron microscopy analysis techniques were used to characterize the samples. it was observed that a thin layer tetragonal sno2 with a disordered porous was embedded on the surface of mwcnts, which resulted in the formation of a novel mesoporous-nanotube hybrid composite. on the base of tem analysis of products from controlled experiment, a possible mechanism was proposed to explain the formation of the mesoporous-nanotube structure. the electrochemical properties of the samples as anode materials for lithium batteries were studied by cyclic voltammograms and galvanostatic method. results showed that the mesoporous-tube hybrid composites displayed higher capacity and better cycle performance in comparison with the mesoporous tin dioxide. it was concluded that such a large improvement of electrochemical performance within the hybrid composites may in general be related to mesoporous-tube structure that possess properties such as one-dimensional hollow structure, high-strength with flexibility, excellent electric conductivity and large surface area. |
