Study on the Synthesis and Mechanism of Mesoporous Silica with Hexastyle Structure

Abstract

Abstract: The mesoporous silica MCM--41 materials with hexastyle structure were synthesized under strongly acidic condition.
The characteristics of samples were investigated by using XRD, N₂ adsorption, HREM, and SEM techniques. The results show
that MCM-41 powder with hexastyle structure, which is wormlike in micrometer-scale, consists of thousands of mesoporous channels in
nano-scale. The morphogenesis of hexastyle mesoporous silica is due to the accretion of surfactant micella combined with silica oligmers
in the low concentration of TEOS.

Key words: mesoporous silica MCM--41, hexastyle, morphogenesis
