Abstract:
An ordered mesoporous silica with novel cubic structure (space group Fd3m) has been synthesized by using tri-head group quaternary ammonium surfactants [CmH2m + 1N+(CH3)2CH2CH2N+(CH3)2CH2CH2CH2N+(-)(CH3)(3).3Br-] (Cm-2-3-1, m = 14, 16, 18) as the structure-directing agents under basic conditions at low temperature.
