Abstract Hierarchical ZSM-5 zeolites were prepared by “Dry Gel Conversion-Steam Assisted Crystallization” (DGC-SAC) procedure without the involvement of additional template. Moreover, the formation mechanism and feather of mesopores were summarized. Nanoscale Kirkendall effect was existed in the growth of zeolite crystals under high SiO2/TPA+ ratio, which was responsible for the production of intra-crystal mesopores. However, small ZSM-5 nano-crystallites, with the average diameter of

干凝胶转化-蒸汽辅助结晶法合成多级ZSM-5沸石及其在甲醇芳构化中的应用

摘要通过“干凝胶转化-蒸汽辅助结晶”(DGC-SAC) 程序制备多级 ZSM-5 沸石，无需额外模板。此外，还总结了介孔的形成机制和羽状结构。在高 SiO2/TPA+ 比下，沸石晶体的生长存在纳米级柯肯德尔效应，这导致了晶内介孔的产生。 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 然而，小的 ZSM-5 纳米微晶，平均直径为
