Synthesis and characterization of functionalized mesoporous ethanesilica

In this paper, different organic group-functionalized mesoporous ethanesilicas have been synthesized by the co-condensation of 1,2-bis-(triethoxysilyl) ethane (BTEE) and organosilanes under basic conditions, using cetyltrimethylammonium bromide (CTAB) as a template. High quality mesoporous materials were obtained with MCM-41-type structure. But the employing of different organic groups, such as vinyl, aminopropyl, glycidoxypropyl, mercaptopropyl, leads to different morphologies. The ratio of organosilane to BTEE also affects the mesostructures and morphologies of the final materials. Using the similar method, Ce-doped mesoporous ethanesilica was also obtained.
