Abstract

MCM-41 type spherical mesoporous silica material was synthesized, under basic conditions, in the presence of cationic surfactant as templating species. The cationic surfactants used in this experiment were octyltrimethylammonium bromide, dodecyltrimetylammonium bromide, cetyltrimethylammonium bromide, octadecyltrimethyammonium bromide and cetylpyridium bromide. Specific surface area of spherical MCM-41 was as high as $1500m^2/g$ and the pore size decreased with increasing alkyl chain length of surfactant.
