【摘要】本文以商用的ZSM-5沸石为原料，采用降解法合成了孔壁含有沸石结构单元的Z-SBA-15介孔分子筛。利用XRD、TEM和SEM技术，考察了温度、时间、ZSM-5的硅铝比、降解液用量和初始凝胶PH值对合成产物的影响，找出适宜的合成工艺条件。通过不同比例混合沸石样品XRD表征，对合成样品结构进行分析，探讨了不同沸石结构单元的XRD表征特性。

[Abstract] Using the commercial ZSM-5 zeolite as raw material, the mesostructured material Z-SBA-15 with pore wall composed of the structure units of zeolite through the dissolution of zeolite was synthesized in this paper.The optimal process conditions for synthesis of Z-SBA-15 were found by experimental research on influence factors for synthesis product, including, temperature,time, silica alumina ratio of ZSM-5, amount of degradation solution, and PH value of initial gelation. The results were studied by analyzing the samples using X-ray diffraction (XRD), Scanning Electron Microscope(SEM), and Transmission Electron Microscopy (TEM). Method to analyze the structure of synthesis product by analyzing the samples of different mixing ratio of zeolite using X-ray diffraction (XRD), and the characterization of different structure units of zeolite were investigated.
