Abstract: 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 CTABis 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 CTABsystem and a well ordered structure of pore array was maintained.
Key words: Mixed surfactants, Liquid crystal template, Meso porous silica
