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 Ｍ４１ 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 Ｍ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 The mesoporous silica M C M41 with hexagonal prism structure was synthesized under strong acidic conditions. The properties of the material were characterized by XRD, N2 adsorption, SEM and HRTEM. The results show that M C M41 material with a hexagonal prism structure on the micrometer scale is composed of nano-pores with regular orientation and orientation. The surface micelles with surface-attached silicate ions are aggregated according to the geometrical structure of the liquid crystal. The main reason for the formation of hexagonal prism mesoporous material
