| 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ＭＣＭ－４１材料，并通过ＸＲＤ、氮气吸附、ＳＥＭ、ＨＲＴＥＭ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棱柱结构的ＭＣＭ－４１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，是导致六方棱柱结构介孔材料形貌生成的主要原因。

| 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, 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 |

| Keywords: | mesoporous silica MCM 41 hexastyle morphogenesis |
