摘要: 配位不饱和金属-有机骨架(MOFs)材料是一种极具潜力的小分子气体吸附分离储存材料。本文回顾了近几年MOFs材料在捕集CO2领域的发展状况,对近年来研究比较集中的几种金属配位不饱和MOFs材料进行了详细的介绍与比较,如MIL系列、Cu-BTC系列及MOF-74等。该工作为系统地认识MOFs和拓展其未来在CO2吸附分离领域的应用提供了帮助。本文同时也进一步指出不饱和金属配位的存在对多孔MOFs材料的吸附性能起着重要作用。在多孔MOFs材料对CO2捕集效果仍不能满足工业需求的现状下,预测合理设计MOFs的金属配位中心且通过活化处理调控MOFs中金属的配位状况,甚至对其孔道表面功能化修饰将是该类型材料的发展方向,并在最后从制备方法、金属中心的选择与表面改性3方面作了总结。

Abstract: MOFs are a kind of potentially ideal adsorbents with coordinative unsaturated metal sites (UMSs). It can be used to separate and store small molecule gas. This article reviewed the development of MOFs materials in CO2 capture in recent years. We summarized some typical coordinatively unsaturated metal-organic materials,such as MIL series,Cu-BTC,MOF-74 and so on,which are suitable for capturing CO2. This work would help us to understand the metal-organic porous materials and expand their application in CO2 capture in the future. At the same time,this paper also pointed out that open metal sites play an important role on the adsorption performance of the porous MOFs materials. At present,the efficiency of porous MOFs materials for CO2 capture is far from the industrial requirement,so reasonable design of MOFs metal center,activating treatment after syntheses and the functionalized modifications on the pore channel surface would be the development directions for these type materials. At the end,we made the conclusions from the aspect of the preparation methods,the metal centers and surface modification.

Key words: coordinatively unsaturated metal sites, MOFs, porous MOFs material, CO2 capture, adsorption, surface modification
