摘　　要：离子热合成法是一种非常有前景的材料合成方法,而空心分子筛由于拥有更大的比表面积和多级结构,其在催化吸收方面的性能更加优良,本论文讨论了分子筛的晶化机理及合成方法及影响其合成的因素,结果表明适当的有机胺、HF及PH更有利于合成空心AlPO_4-5分子筛。并对空心分子筛在吸附、催化等方面的应用前景进行了展望。The method of ion thermal synthesis is promising. Hollow molecular sieve with large surface area and multi-level structure has more excellent catalytic and absorption performance. In this paper, the crys- tallization mechanism and synthesis method of molecular sieves and the factors influencing their synthesis were discussed. The results showed that the proper organic amine, HF and PH were more favorable for the synthesis of hollow A1PO4-5 zeolite. And hollow zeolite application in terms of adsorption, catalysis is prospected.
