| 摘 要： | 以具有微孔结构的乙二醇钛(TG)为前驱体, 采用无模板法制备了一系列单分散的介孔TiO2纳米球. 通过溶剂热处理, 微孔前驱体TG原位水解直接转化为具有介孔结构的TiO2纳米球. 通过X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱(FTIR)及氮气吸附-脱附等对产物进行了表征. 测试结果表明, 产物具有高结晶性、均一的形貌、可调的孔径和比表面积.

| Abstract: | We report a facile template-free method to fabricate monodisperse mesoporous TiO2 spheres using microporous titanium glycolates(TG) as precursor. By solvothermal treatment, microporous TG can be directly converted into mesoporous TiO2 spheres via in-situ hydrolysis. The products were characterized by XRD, SEM, TEM, FTIR and nitrogen absorption. The results show that the products exhibit high crystallinity, uniform morphology and tunable pore size. These integrated features would make the as-obtained mesoporous TiO2 materials have attractive applications in areas of environmental purification, energy conversion and storage. |
