Abstract:
Cubic mesoporous titanium-containing silica(TiMCM48) can be synthesized by using mixed surfactants CTAB-CnNH2(n=8,10,12,14) as templates in basic medium. Characterization results obtained from the determination of XRD, TEM and N 2adsorption show that the products possess high-quality TiMCM48.The effect of the chain length of the alkylamine and the ratio of titanium to silicium on the structure of the cubic mesophases were investigated. It was revealed that the mesophase transition from cubic to lamellar structure occurred with increasing alkylamine chain length and Ti/Si ratio.
Key words: Mixed surfactant templating, Cubic structure, Mesoporous titanium-containing silica
