中文摘要：

以钛酸丁酯（TBT）为钛源，离子液体1-正己基-3-甲基咪唑溴盐（HmimBr）为模板剂和老化液，采用溶胶一凝胶法在低温常压下制备了锐钛矿相TiOz气凝胶。通过XRD、FT—IR、BET等方法对样品进行表征。结果表明，以2．5mol／L的[Hmim2Br作为老化液所制备的样品具有最佳的性能参数，其块体尺寸、比表面积、平均孔径和孔体积分别为14mm、208．1m2／g、28．13nin及0．293Cm2／g。

The titanium resource and 1 sol-gel method hexyl-3 dioxide aerog methylimidazo els were succes in low temperature and no XRD, FT-IR and BET. The showed the best performance, Bromide rmal pres sfully prepared with tetrabutyl tit Hmim]Br） as a template and aging sures. The aerogel results showed that the prepared sampl volume were 14 mm, 208.1 m2 samples were char e with 2.5 mol/L anate as Ti solution by acterized by [Hmim]Br in which the size, specific surface area, average pore diameter and pore /g, 28.13 nm and 0. 293 cm3/g respectively.
