Porous solids containing internal pores with sizes ranging from angstroms to nanometers are highly useful and valuable in the catalysis, separation, and storage of molecules because these materials provide large surface areas and void spaces for the interaction and adsorption of molecules. In particular, two-dimensional zeolites (2D, sometimes called layered zeolites) with layer thickness of 2–3 nm (1–2 unit cells) have enabled the synthesis of advanced materials and their application in catalysis for the transformation of bulky substrates unable to enter zeolite pores, thereby substantially increasing the number of zeolite applications and modifications. Accordingly, this Review aims to highlight recent developments in the synthesis, characterization, and application of 2D zeolites, focusing on the two most important representatives, MWW and MFI.

MWW和MFI框架作为模型分层沸石：结构，转变，特性和活动

包含尺寸从埃到纳米的内部孔的多孔固体在分子的催化，分离和存储中非常有用且有价值，因为这些材料为分子的相互作用和吸附提供了大的表面积和空隙。特别是二维沸石（2D有时称为分层沸石），其层厚为2–3 nm（1-2个晶胞），能够合成高级材料并将其用于催化无法转化的大体积底物。进入沸石孔，从而大大增加了沸石的应用和改性数量。因此，本评论旨在重点介绍2D沸石的合成，表征和应用方面的最新进展，重点是两个最重要的代表，MWW和MFI。
