摘要/Abstract

摘要： 先以硅烷偶联剂3氨丙基三乙氧基硅烷（APTES）为软模板剂, 用软模板法制备含介孔结构的ZSM-5沸石分子筛；然后用Fourier变换红外光谱(FT-IR)、 X射线衍射(XRD)、 N₂吸附脱附及透射电镜(TEM)等方法对制备的样品进行表征, 考察APTES添加量对合成样品孔结构的影响；最后用模型反应苯酚分析其酸催化性能.

Abstract: Using 3aminopropyltriethoxysilanes (APTES) as soft template, we prepared mesoprous ZSM-5 zeolite molecular sieve by soft template method. The samples were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N₂ adsorptiondesorption and transmission electron microscope (TEM), etc. The effect of adding amount of APTES on the pore structure of the synthesized samples was investigated. The acid catalytic performance of the synthesized sample
s was analyzed by model reaction of phenol.

Key words: mesoporous ZSM-5 zeolite, 3-aminopropyltriethoxysilanes (APTES), hierarchical pore
