摘　　要：核壳型沸石反应器由于其独特的双层结构、沸石壳的筛分及保护作用以及多重催化功能,成为当前催化与纳米材料研究的一个热点。催化反应中,核壳型沸石反应器往往可以进行多步催化以及筛分,将原本的多步反应变为一步反应,大大提高了催化反应的产率以及选择性。本文主要论述核壳型沸石反应器的结构及其在石油化工、煤化工以及精细有机反应中的应用,并对核壳型沸石反应器的发展前景进行展望。Owing to the unique structures, the core-shell zeolite reactors exhibit the excellent molecularsieving effect for the reactant and product, anti-poison and anti-leaching of the active sites, and integration of multiple catalytic functions in a material. They are believed as the promising catalysts for their greatly improved activity, selectivity and stability. In this paper, we mainly discuss their structure, preparation and application in petrochemical industry, coal chemical industry and fine organic reactions. Their development prospects are also discussed.
