Mixed‐matrix membranes (MMMs) have been studied widely in the field of gas separation due to their potential to overcome performance barriers found in traditional polymeric membranes. Most polymeric membranes exhibit a trade‐off between permeation and selectivity, which has limited their development in many challenging separation applications. One solution to this issue utilizes the introduction of fillers into the polymer matrix to produce MMMs. Out of the many different fillers, metal–organic frameworks stand out as a promising candidate due to their highly tunable structure, molecular sieving effect, and superior compatibility with the polymer matrix. This review will provide an in‐depth look into the basic mechanisms of MMMs for gas separation and different approaches to model the permeation of gases through the membrane. In addition, challenges facing the field and recent research trends for MMMs will be discussed as well as their many applications for different gas separations. Finally, some insight on the future direction for MMMs will be covered, focusing on many intriguing opportunities and challenges that must be further explored to advance this technology.

基于金属-有机框架的混合基质膜用于气体分离：概述

混合基质膜（MMM）在气体分离领域已被广泛研究，因为它们具有克服传统聚合物膜中存在的性能障碍的潜力。大多数聚合物膜在渗透率和选择性之间进行权衡，这限制了其在许多具有挑战性的分离应用中的发展。解决该问题的一种方法是将填料引入聚合物基体中以生产MMM。在许多不同的填料中，金属有机骨架因其高度可调的结构，分子筛作用以及与聚合物基质的优异相容性而成为有前途的候选者。这篇综述将深入探讨MMMs用于气体分离的基本机理，以及模拟气体通过膜渗透的不同方法。此外，将讨论MMM领域面临的挑战和最新研究趋势，以及它们在不同气体分离中的许多应用。最后，将涵盖对MMM未来方向的一些见解，重点关注许多有趣的机遇和挑战，必须进一步探索以推动该技术的发展。
