摘要： 采用双子型季铵盐类阳离子表面活性剂溴代Gemini1231做模板剂，用溶胶-凝胶（sol-gel）法在室温合成了介孔TiO2材料，用TG-DTA、XRD、N2吸附-脱附、TEM等进行表征.结果表明，用该模板剂合成的介孔TiO2材料，合适的煅烧温度为480℃，其比表面积可达383.8m2/g，最可几孔径为5.8nm，广角XRD测试发现较强的锐钛矿型特征峰，而未发现金红石相特征衍射峰，说明本实验制备的介孔TiO2为稳定锐钛矿型.通过小角X射线衍射分析发现，产物具有规整有序的介孔结构.

Abstract: Using Gemini231 quaternary ammonium salts cationic surfactant as template, mesoporous titanium dioxide material was synthesized by sol-gel method at room temperature. The synthesized samples were investigated by thermogravimetic-differential thermal analysis, X-ray diffraction, nitrogen adsorption-desorption and transmission electron microscope(TEM) techniques. The results show that the obtained mesoporous TiO2 calcined at 480℃ have a high specific surface area up to 383.8m2·g1 , and a mean pore size of about 5.8nm in diameter, and crystallized anatase framework. No rutile phase is found. Small-angle X-ray diffraction analysis shows that the sample has an ordered mesoporous structure.
