Abstract: Different structural mesoporous silicas have been synthesized at high temperature using the Stöber method by utilizing a mixture of cationic cetyltrimethylammonium bromide and anionic water-soluble sodium polyacrylate (NaPAA) as template. The synthetic conditions, which include the amount of ethanol, crystallization temperature, crystallization time, polymer concentration, and molecular weight, have significant influence on the structures and surface morphologies of the synthetic product. This could be attributed to a combined effect of NaPAA and ethanol.

Key words: cationic surfactant, anionic polymer, composite template, ethanol, mesoporous silica
