基于从废气中脱除回收CO2的迫切现实需求,通过对金属有机框架材料(MOFs)进行功能化修饰,构筑具有高容量、高选择性CO2吸附的耐水MOFs材料成为当前的研究热点。本文首先对MOFs材料的高压CO2吸附进行了简单的介绍;进而,针对实际工业应用中低压条件下的CO2捕集,对作为调节MOFs材料CO2低压吸附分离性能的有效手段的含氮以及杂原子极性基团修饰进行了综述。
Based on the urgent practical needs for removal and recovery of CO2 from the exhaust gas,it is one of research hotspots to construct functional MOFs with water resistance,high capacity and separation for CO2 adsorption.In this paper,the high pressure CO2 adsorption of MOFs materials is briefly summarized,and taking into account the actual industrial application conditions,recent progress in low pressure CO2 adsorption and separation by MOFs which have been decorated with nitrogen or heteroatom-containing polar functional groups is highlighted.
