摘　　要：ZIF-8膜是一种新型的金属有机框架材料纳米多孔材料。由于其独特的蜂窝状多孔结构以及优良的热稳定性和化学稳定性,近年来在气体分离领域得到了广泛应用。ZIF-8膜的孔径介于氢气和其他气体(如氮气、甲烷等)的动力学直径之间,使其特别适合用于氢气的分离。本文综述了连续ZIF-8膜的制备方法,重点介绍了近十年来有代表性的原位生长法、二次晶种法、表面修饰法和一些特殊的制备方法。整理并比较了这些方法所制备的连续ZIF-8膜的氢气分离性能以及各方法的优缺点。同时,对原位生长法、二次晶种法和表面修饰法的合成机理进行了详细总结。此外,还简要讨论了未来的研究方向和挑战。The ZIF-8 membrane represents a novel class of metal-organic framework(MOF)materials characterized by nanoporous structure.Due to its distinctive honeycomb-like porous structure and remarkable thermal and chemical stability,ZIF-8 membranes have gained significant traction in the field of gas separation in recent years.The pore size of ZIF-8 membranes lies between the kinetic diameters of hydrogen and other gases(e.g.,N2,CH4,etc.),rendering them particularly suited for the separation of hydrogen.This paper reviewed the preparation methods of continuous ZIF-8 membranes with a focus on the in-situ growth method,the secondary crystal seeding method,the surface modification method and some special preparation methods that were represented in the last decade.This review presented a comparative analysis of the hydrogen separation performance of continuous ZIF-8 membranes prepared by the aforementioned methods along with an evaluation of the advantages and disadvantages associated with each method.In parallel,the synthesis mechanisms of the in-situ growth method,the secondary crystal seeding method and the surface modification method were presented in detail.Furthermore,prospective avenues for future research and the associated challenges are briefly outlined.
