Membrane-based separations have garnered considerable attention owing to their high energy efficiency, low capital cost, small carbon footprint, and continuous operation mode. As a class of highly porous crystalline materials with well-defined pore systems and rich chemical functionalities, metal-organic frameworks (MOFs) have demonstrated great potential as promising membrane materials over the past few years. Different types of MOF-based membranes, including polycrystalline membranes, mixed matrix membranes (MMMs), and nanosheet-based membranes, have been developed for diversified applications with remarkable separation performances. In this comprehensive review, we first discuss the general classification of membranes and outline the historical development of MOF-based membranes. Subsequently, particular attention is devoted to design strategies for MOF-based membranes, along with detailed discussions on the latest advances on these membranes for various gas and liquid separation processes. Finally, challenges and future opportunities for the industrial implementation of these membranes are identified and outlined with the intent of providing insightful guidance on the design and fabrication of high-performance membranes in the future.
基于膜的分离因其高能量效率、低资本成本、小的碳足迹和连续操作模式而受到广泛关注。作为一类具有明确孔系统和丰富化学功能的高度多孔结晶材料，金属-有机骨架（MOFs）在过去几年中作为有前途的膜材料显示出巨大的潜力。不同类型的基于 MOF 的膜，包括多晶膜、混合基质膜（MMM）和基于纳米片的膜，已经为多样化的应用开发，具有显著的分离性能。在这篇全面的综述中，我们首先讨论了膜的一般分类，并概述了基于 MOF 的膜的历史发展。随后，特别关注基于 MOF 的膜的设计策略，并详细讨论了这些膜在各种气体和液体分离过程中的最新进展。最后，确定了这些膜在工业实施方面的挑战和未来机遇，并概述了未来设计和制造高性能膜的有价值的指导。
