Better and more efficient membranes are needed to face imminent and future scientific, technological and societal challenges. New materials endowed with enhanced properties are required for the preparation of such membranes. Metal and Covalent Organic Frameworks (MOFs and COFs) are a new class of crystalline porous materials with large surface area, tuneable pore size, structure, and functionality, making them a perfect candidate for membrane applications. In recent years an enormous number of articles have been published on the use of MOFs and COFs in preparation of membranes for various applications. This review gathers the work reported on the synthesis and preparation of membranes containing MOFs and COFs in the last 10 years. Here we give an overview on membranes and their use in separation technology, discussing the essential factors in their synthesis as well as their limitations. A full detailed summary of the preparation and characterization methods used for MOF and COF membranes is given. Finally, applications of these membranes in gas and liquid separation as well as fuel cells are discussed. This review is aimed at both experts in the field and newcomers, including students at both undergraduate and postgraduate levels, who would like to learn about preparation of membranes from crystalline porous materials.
为应对迫在眉睫的以及未来的科学、技术和社会挑战,需要性能更优、效率更高的膜。制备此类膜需要具有增强性能的新材料。金属有机框架材料(MOFs)和共价有机框架材料(COFs)是一类新型的晶体多孔材料,具有大表面积、可调节的孔径、结构和功能,使其成为膜应用的理想候选材料。近年来,已经发表了大量关于MOFs和COFs在制备各种应用膜方面的文章。本综述收集了过去10年中有关含MOFs和COFs膜的合成与制备的报道。在此,我们概述了膜及其在分离技术中的应用,讨论了其合成中的关键因素及其局限性。给出了用于MOF和COF膜的制备和表征方法的详细总结。最后,讨论了这些膜在气体和液体分离以及燃料电池中的应用。本综述面向该领域的专家和新手,包括本科和研究生阶段希望了解从晶体多孔材料制备膜的学生。
