Synthesis and Electrochemical Performance of Porous TiO2
Source abstract
Abstract
以介孔碳为模板, 成功合成了具有较大比表面积的多孔TiO 2 , 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.
