摘　　要：概述了核壳型沸石分子筛的合成、表征和催化应用等方面的最新研究成果,总结了其结构特点与分类、制备方法和合成过程关键影响因素,并展望了核壳型沸石分子筛研究的发展方向和其在催化、吸附和分离方面的应用前景。根据其合成方法和两相结构类型的异同,核壳型沸石分子筛可分为三类:同晶型核壳沸石分子筛、外延共生型核壳沸石分子筛和复合型核壳沸石分子筛。Core-shell zeolite composites possess an active core and a tiny shell. This paper summarized the recent advances in the syntheses, characterizations, and catalytic applications of core-shell type zeolite materials, including the classification and structural features, synthetic methodologies, and the factors controlling the formation of core-shell zeolite composites. The developing trends and potential application perspectives were also discussed.
