In the past decade, a huge development in rational design, synthesis, and application of molecular sieve membranes, which typically included zeolites, metal-organic frameworks (MOFs), and graphene oxides, has been witnessed. Owing to high flexibility in both pore apertures and functionality, MOFs in the form of membranes have offered unprecedented opportunities for energy-efficient gas separations. Reports on the fabrication of well-intergrown MOF membranes first appeared in 2009. Since then there has been tremendous growth in this area along with an exponential increase of MOF-membrane-related publications. In order to compete with other separation and purification technologies, like cryogenic distillation, pressure swing adsorption, and chemical absorption, separation performance (including permeability, selectivity, and long-term stability) of molecular sieve membranes must be further improved in an attempt to reach an economically attractive region. Therefore, microstructural engineering and architectural design of MOF membranes at mesoscopic and microscopic levels become indispensable. This review summarizes some intriguing research that may potentially contribute to large-scale applications of MOF membranes in the future.
在过去的十年中，人们见证了分子筛膜在理性设计、合成和应用方面的巨大发展，这些膜通常包括沸石、金属-有机骨架（MOF）和氧化石墨烯。由于在孔径和功能方面具有很高的灵活性，MOF 以膜的形式为节能气体分离提供了前所未有的机会。2009 年首次报道了具有良好生长的 MOF 膜的制备。此后，该领域取得了巨大的发展，MOF 膜相关出版物也呈指数级增长。为了与其他分离和净化技术（如低温蒸馏、变压吸附和化学吸收）竞争，分子筛膜的分离性能（包括渗透性、选择性和长期稳定性）必须进一步提高，以达到具有吸引力的经济区域。因此，MOF 膜在介观和微观水平上的微观结构工程和建筑设计变得不可或缺。本文综述了一些可能有助于 MOF 膜在未来大规模应用的有趣研究。
