A new highly ordered mesostructured silica (possible space group Fm3m) was synthesized by using tri-headgroup quaternary ammonium surfactant CH3(CH2)17N+(CH3) 2CH2CH2N+(CH3) 2CH2CH2 CH2N,+ (CH3)3 • 3Br- (C18-2-3-1) 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.
