摘要：

Using the mixture of cationic surfactant cetyltrimethylammonium bromide(CTAB) and six nonionic surfactants as templates, meso porous silica was synthesized. The d space of silica templated by CTAB is 3.5 nm. The d spaces could be controlled by changing the ratio of nonionic to cationic surfactants and by increasing the length of nonpolar chain of nonionic surfactants in the mixed cationic nonionic surfactant templating systems. The pore dimension of silica in the mixed surfactants templating system is larger than that in CTAB system and a well ordered structure of pore array was maintained. [WT5HZ]
