摘　　要：利用绿色非离子表面活性剂烷基糖苷APG08-10和阳离子表面活性剂十八烷基三甲基氯化铵1831为复合模板剂,正硅酸乙酯为硅源,导向制备出笼状介孔二氧化硅。通过氮气物理吸附、透射电镜对其结构进行表征,得到比表面积S BET 540.2 m^(2)/g,孔容0.72 m 3/g,孔径3.8 nm,粒径90 nm左右的笼状介孔二氧化硅纳米材料。Using the green nonionic surfactant alkyl glycoside APG08-10 and the cationic surfactant octadecyl trimethylammonium chloride 1831 as composite template agents,and ethyl orthosilicate as the source of silicon,caged mesoporous silica is prepared.The structure is characterized by N 2 physical adsorption and transmission electron microscopy.It is obtained that the specific surface area S BET is 540.2 m^(2)/g,pore capacity is 0.72 m 3/g,aperture is 3.8 nm,and the particle size of cage-shaped mesoporous silica nanomaterials is about 90 nm.
