The booming of global environmental awareness has driven the scientific community to search for alternative sustainable approaches. This is accentuated in the 13th sustainable development goal (SDG13), climate action, where urgent efforts are salient in combating the drastic effects of climate change. Membrane separation is one of the indispensable gas purification technologies that effectively reduces the carbon footprint and is energy-efficient for large-scale integration. Metal-organic frameworks (MOFs) are recognized as promising fillers embedded in mixed matrix membranes (MMMs) to enhance gas separation performance. Tremendous research studies on MOFs-based MMMs have been conducted. Herein, this review offers a critical summary of the MOFs-based MMMs developed in the past 3 years. The basic models to estimate gas transport, preparation methods, and challenges in developing MMMs are discussed. Subsequently, the application and separation performance of a variety of MOFs-based MMMs including those of advanced MOFs materials are summarized. To accommodate industrial needs and resolve commercialization hurdles, the latest exploration of MOF materials for a harsh operating condition is emphasized. Along with the contemplation on the outlook, future perspective, and opportunities of MMMs, it is anticipated that this review will serve as a stepping stone for the coming MMMs research on sustainable and benign environmental application.
全球环境意识的蓬勃发展促使科学界寻求替代的可持续方法。这在第 13 个可持续发展目标（SDG13）——气候行动中尤为明显，迫切需要采取紧急行动来应对气候变化的剧烈影响。膜分离是一种不可或缺的气体净化技术，可有效减少碳足迹，并具有大规模集成的节能优势。金属-有机框架（MOFs）被认为是嵌入混合基质膜（MMM）中的有前途的填充材料，可提高气体分离性能。已经对基于 MOF 的 MMM 进行了大量的研究。本文对过去 3 年开发的基于 MOF 的 MMM 进行了批判性总结。讨论了用于估计气体传输的基本模型、制备方法以及开发 MMM 的挑战。随后，总结了各种基于 MOF 的 MMM 的应用和分离性能，包括先进的 MOF 材料。为了满足工业需求并解决商业化障碍，强调了对苛刻操作条件下 MOF 材料的最新探索。本文还对 MMM 的未来展望、机会进行了思考，预计这将为可持续和良性环境应用的未来 MMM 研究铺平道路。
