摘要
在强酸性条件下合成了具有六方棱柱结构的介孔氧化硅 Ｍ Ｃ Ｍ４１ 材料， 并通过 Ｘ Ｒ Ｄ、氮气吸附、 Ｓ Ｅ Ｍ、 Ｈ Ｒ Ｔ Ｅ Ｍ 等手段对材料性能进行了表征结果表明： 在微米尺度上具有六方棱柱结构的 Ｍ Ｃ Ｍ４１ 材料， 是由定向规则排列的纳米孔道组成表面附着硅酸根离子的表面活性剂胶束按照液晶几何构造定向聚集生长，
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
