中文摘要：

二维层状分子筛前驱体具有三维分子筛的层结构单元,具备母体分子筛的特性,其开放二维片层骨架结构给合成新分子筛以及基于其改性得到新衍生结构分子筛提供新机遇,是近年来分子筛研究领域一个新热点。大量二维片层前驱体可直接合成或通过三维分子筛后处理获得,基于二维片层前驱体人们发展了溶胀、剥层、柱撑、原子扩孔、层重组等层操纵的策略,通过这些策略一些常规方法难以合成或不符合理论规则的分子筛被合成出来,这极大地丰富了二维层状分子筛前驱体的研究领域,扩展了其应用范围。本文概述了二维层状分子筛前驱体的结构特点,系统总结了近年来二维层状分子筛前驱体的合成方法,在此基础上着重阐述了其改性获得新结构分子筛的新策略,并介绍了在多相催化反应中的应用。

英文摘要：

Two-dimensional layered zeolite precursors （LZPs） with layered structural units of parent threedimensional zeolites possess the properties of the parent materials but with an open framework structure. The structural properties of these materials therefore provide new opportunities to synthesize new zeolites and fabricate sub-zeolites with distinct structures, making them a hot topic in zeolite research. Enormous LZPs were synthesized by the direct crystallization or post-modification of their three-dimensional parent structures. Several layer manipulation strategies, including swelling, delamination, pillaring and layer reassembly have been developed on two-dimensional LZPs. These strategies have provided access to zeolites with new structures as well as materials even violating the theoretical rules, which have greatly enhanced the field of two-dimensional LZPs, and expanded their applications in catalysis and separation. Herein, we have reviewed the structural characteristics of two-dimensional LZPs, as well as summarizing their syntheses, modifications, and catalytic applications. We have also proposed the future perspectives of two-dimensional LZPs.
