| 摘 要： | MCM-41分子筛是具有单一孔径的长程有序介孔材料,由于孔壁是无定形结构,与微孔沸石晶体相比,水热稳定性较差,这使其在石油炼制和精细化工中的应用受到很大的限制.根据实验发现,如果将一些沸石的前驱结构单元体--即在形成完整的沸石结构前所形成的初级或次级结构单元引入介孔材料,使其转化为介孔孔壁,将会增加介孔材料的短程有序化程度,提高水热稳定性.

| Abstract: | Mesoporous Molecular Sieves were successfully synthesized by using the performed zeolite mordenite precursors as silica source. The synthesized samples were characterized by XRD, FT-IR , N2 adsorption and desorption and hydrothermal treatment methods. The results demonstrated that the synthesized samples were similar to the conventional structure MCM-41 in the ordered hexagonal structure and were superior to conventional MCM-41 with respect to their higher hydrothermal stability. It is suggested that secondary structure units of mordenite zeolite were introduced into the mesoporous wall that makes the contribution of the highly hydrothermal stability of Mesoporous Molecular Sieves. |
