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.
