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。

Abstract:

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.

Key words: continuous ZIF-8 membrane, hydrogen separation, in-situ growth method, secondary crystal seed method, carrier surface modification method
