中文摘要：

首先利用脂肪醇聚氧乙烯醚硫酸钠（AES）与十六烷基三甲基溴化铵（C’FAB）在水溶液中自组装形成囊泡体系，然后住囊泡体系中pH=9．2条件下以正硅酸四乙酯（TEOS）作为硅源，合成了介孔二氧化硅。用动态光散射仪（DLS），透射电镜（TEM），X射线衍射仪（XRD）和低温氮吸附仪等对囊泡体系和介孔二氧化硅样品进行了表征。结果表明，在浓度均为0．01tool·L“的AES溶液与CTAB溶液体积比为1：1时得到了直径约为50nm的囊泡体系。在2．88。处出现了介孔二氧化硅材料的特征衍射峰。测得介孔二氧化硅材料的平均孔径为3.5nm，比表面积为670m^2·g^-1。

英文摘要：

Self- assembly vesicle system was prepared by utilizing sodium fatty alcohol ether sulfate （AES） and cetyltrimethylammonium bromide （CTAB） as starting materials. Then mesoporous silica was synthesized in the vesicle system with tetraethyl ortho silicate （TEOS） as silicon source under condition of pH = 9.2. The synthesized vesicle system and the mesoporous silica were characterized by dynamic light scattering photometer （DLS）, transmission electron microscope （TEM）, X -ray diffractometer （XRD） and N2 adsm＇ption - desorption. Experimental resuhs showed that tinder condition as volume ratio of AES aqueous solution to CTAB aqueous solution 1： 1, both with concentration of 0.01 mol · L^-1, vesicle system with diameter of 50 nm can be obtained. Characteristic diffraction peak appears at angle of 2. 88°. Average pore diameter of the mesoporous silica material was measured as 3.5 mn and specific surface area of tile material was measured as 670 m2 · g ^-1
