Abstract: Two-dimensional (2D) zeolite nanosheets, which combine an ultra-large external surface area with intracrystalline microporous channels, can effectively alleviate diffusion limitation. Their controllable preparation have attracted widespread attention. Herein, the syntheses of representative MWW, MFI, and FER 2D zeolite nanosheets, along with strategies to construct interlayer architectures using nanosheet layers, are systematically summarized, including post-treatment methods such as swelling-exfoliation/pillarization, the use of special organic structure-directing agents, and direct crystallization assisted by organic/inorganic additives. The characteristics of different methods in terms of structural control and scalable production are also analyzed. Finally, the challenges in the synthesis of 2D zeolite nanosheets are summarized, and future directions for development are prospected.

Key words: two-dimensional zeolite nanosheets, organic structure-directing agent, ADOR method, swelling-delamination, additive-assisted crystallization synthesis, post-treatment synthesis
