有机多孔聚合物CO2捕集及分离性能的研究进展

摘要

有机多孔聚合物（porous organic polymers，POPs）是一类由有机构建单元连接而形成的新型多孔材料。由于其优异的物理化学稳定性以及CO2吸附能力，近年来有关POPs在CO2捕集和分离的研究成为一大研究热点。大量具有优异孔性质（比表面积和孔容）的POPs通过不同有机合成反应被成功地开发出来应用于CO2吸附分离过程。本文介绍了POPs材料的CO2捕集与分离性能的研究现状，总结了提高POPs材料CO2分离性能的合成策略，重点分析了可以通过功能化增强吸附剂与二氧化碳分子之间的相互作用，来提高材料的CO2分离能力的方法。%Porous organic polymers (POPs), a new type of porous materials constructed by organic building blocks, have attracted attention and shown significant potential for CO2 capture and separation due to their high physicochemical stability and excellent adsorption capacity. Numerous POPs with good porosity (both surface area and pore volume) are preparedvia different organic reactions. The progress of capture and separation of CO2 by POPs is reviewed. Several potential strategies like increasing isosteric heats between sorbent and CO2 molecules by chemical functionalization for enhancing CO2 separation performance are summarized.
