中文摘要：

本研究采用有机硅烷偶联N-甲基十八烷基[3-（三甲氧基硅基）丙基]氯化铵（TPOAC）作为中孔模板剂，在水热条件下合成了具有FAU结构的中孔X和Y型沸石，并用x射线衍射、扫描电镜、透射电镜、氮气吸附／脱附和热重分析技术对合成样品进行了结构表征。结果表明，在该沸石合成体系中TPOAC的加入使沸石晶粒纳米化，同时可在沸石晶粒内部创造丰富的直径为5～6nm的中孔，并且改变了沸石晶体的外观形貌。从而获得了不仅保持沸石固有微孔、同时具有晶内中孔和晶间中孔的介孔FAU沸石。

英文摘要：

Mesoporous zeolites X and Y with FAU structure were hydrothermally synthesized using an organos- ilane surfactant （TPOAC） as mesopore-generating agent, which was added into the conventional synthesis system of the crystalline microporous aluminosilicates. X-ray diffraction, scanning electron microscope, high-resolution transmission electron microscope, N2 adsorption-desorption isotherms and therrnogravimetric analysis were used to characterize their structural and textural features. The results showed that the presence of TPOAC led to nanoscale zeolite crystals and abundant intracrystal mesopores at diameter of 5-6 nm, forming the meso-zeolites X and ~ with micropores, intra- and inter-mesopores. Both mesoporous zeolite X and Y displayed not only inherent topological and microporous structure of zeolite FAU, but also different morphology from conventional zeolite FAU crystals.
