Two-dimensional (2D) metal-organic framework (MOF) nanosheets are attracting increasing research attention due to their unique properties originating from their ultrathin thickness, large surface area and high surface-to-volume atom ratios. Many great advances have been made in the synthesis and application of 2D MOF nanosheets over the past few years. In this review, we summarize the recent advances in the synthesis of 2D MOF nanosheets by using top-down methods, e.g. sonication exfoliation, mechanical exfoliation, Li-intercalation exfoliation and chemical exfoliation, and bottom-up methods, i.e. interfacial synthesis, three-layer synthesis, surfactant-assisted synthesis, modulated synthesis, and sonication synthesis. In addition, the recent progress in 2D MOF nanosheet-based nanocomposites is also briefly introduced. The potential applications of 2D MOF nanosheets in gas separation, energy conversion and storage, catalysis, sensors and biomedicine are discussed. Finally, we give our personal insights into the challenges and opportunities for the future research of 2D MOF nanosheets and their composites.
二维（2D）金属有机骨架（MOF）纳米片因其超薄厚度、大表面积和高表面积与体积原子比而具有独特的性质，引起了越来越多的研究关注。在过去的几年中，二维 MOF 纳米片的合成和应用取得了许多重大进展。在本文中，我们总结了近年来通过自上而下的方法（例如超声剥离、机械剥离、插层剥离和化学剥离）和自下而上的方法（即界面合成、三层合成、表面活性剂辅助合成、调制合成和超声合成）合成 2D MOF 纳米片的最新进展。此外，还简要介绍了基于 2D MOF 纳米片的纳米复合材料的最新进展。讨论了 2D MOF 纳米片在气体分离、能量转换和存储、催化、传感器和生物医学中的潜在应用。最后，我们对二维 MOF 纳米片及其复合材料的未来研究的挑战和机遇提出了个人看法。
