Abstract

Mesoporous aluminosilicate material with different Si/Al ratios was synthesized from tetraethylorthosilicate (TEOS) and aluminum nitrate nonahydrate (ANN) via sol-gel route. CTAB was used as the structure-directing agent to create mesopore within the colloidal particles. The pore structure of the finally obtained samples changed regularly with the altering of Si/Al ratio by carefully controlling of the sol-gel process. Bimodal pore structure was then obtained when the Si/Al ratio reached a suitable range. As a result of the sol-gel synthesis method and the templating function of CTAB, nanometer mesoporous molecular sieves were obtained. Structural properties of the samples were characterized by means of XRD, BET, NMR and HRTEM.
