摘要/Abstract

摘要： 以介孔碳为模板, 成功合成了具有较大比表面积的多孔TiO₂, 并研究了煅烧时间对所获材料结构及电化学性能的影响. 采用X射线粉末衍射、场发射扫描电镜、高分辨透射电镜、氮气吸附?脱附实验和电化学测试对合成的材料进行了表征. 测试结果表明所合成的材料是由很小的纳米颗粒组成, 表面积大, 孔分布窄. 经500℃热处理2h的样品为锐钛矿型, 继续延长热处理时间至12h, 所得样品出现了金红石相, 且12h所得材料的初始容量高于2h所得样品, 这可能和样品的结晶度有关.

Abstract: A kind of nanostructure TiO₂ with large surface area was synthesized successfully by using mesoporous carbon as sacrificial template. The effects of annealing time on the morphologies and electrochemical performances of the as-prepared samples were studied. The as-prepared material was characterized by X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM), High-resolution transmission electron microscope (HRTEM), Nitrogen adsorption and desorption experiments and electrochemical measurements systematically. The results show that the as-synthesized TiO₂ is composed of nanoparticles, which has a narrow porous distribution with high specific surface area. It is also found that the sample synthesized at 500℃ for 2 h is pure anatase TiO₂, when the sintering time is prolonged to 12 h, there is a trace amount of rutile phase coexisted with the anatase phase. However, the sample sintered for 12 h exhibits higher initial capacity than that of the sample sintered for 2 h, which may be caused by different crystallization of samples.

Key words: TiO₂, mesoporous carbon, lithium ion batteries
