Abstract: A new highly ordered mesostructured silica(possible space group Fm3m) was synthesized by using triheadgroup quaternary ammonium surfactant CH3(CH2)17N+(CH3)2CH2CH2N+(CH3)2CH2CH2CH2N+(CH3)3·3Br-(CM18-2-3-1) under a basic condition. The cubic mesoporous silica product has an average pore size of 2.9 nm, a large BET specific surface area of 991 m2/g and a large pore volume of 0.98 cm3/g.

Key words: Template, Mesoporous molecular sieves, Synthesis
