摘要
气体分离在石油化工和化工生产中有非常重要的作用。沸石咪唑酯骨架(ZIFs)作为一种新型的多孔材料,具有大比表面积、高孔隙率、多样的结构组成和超高的热稳定及化学稳定性,成为该领域的研究热点。本文围绕ZIFs材料的合成展开,详尽地总结了现阶段ZIFs在气体吸附分离领域的应用,重点介绍ZIFs在工业CO_2捕获及分离、轻质烃分离、气相色谱分离、用于气体分离的ZIFs基膜、惰性气体分离和有毒气体分离等行业的研究进展。同时指出,ZIFs材料在气体吸附分离领域的应用仍需要进一步研究,如新型低成本配体的开发、探索更多的合成方法来调整晶体结构、提升ZIFs材料的吸附效率,才能使ZIFs从实验室走向工业化。
Gas separation plays a crucial role in petrochemical engineering and chemical production.Zeolitic imidazole frameworks(ZIFs), as a new type of porous material, has become a research hotspot in gas separation because of its large surface area, high porosity, various structural compositions, and super high chemical and thermal stability. In this paper, the synthesis methods of ZIFs and its applications in adsorption and separation are reviewed. This article focuses on the progress in industrial CO2 capture and separation, light hydrocarbon separation, gas chromatography, ZIFs based membrane, inert and toxic gas separation. It is also pointed out that the application of ZIFs in the gas adsorption and separation field still needs further study, such as developing novel low-cost ligands, exploring more synthesis methods to adjust the crystal structure, and enhancing the adsorption efficiency.
