Study on the Synthesis and Mechanism of Mesoporous Silica with Hexastyle Structure
六方棱柱结构介孔氧化硅材料的合成及其机制探讨

The mesoporous silica MCM 41 materials with hexastyle structure were synthesized under strongly acidic condition The characteristics of samples were investigated by using XRD, N 2 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
