Research progress on adsorption and catalytic conversion of CO_2 by functionalized microporous organic polymers

CO_2既是温室气体的重要组分,又是可再生的C1资源,随着温室效应导致的全球变暖等环境问题的加剧,CO_2化学引起科学家越来越多的关注.微孔有机聚合物材料(MOPs)所具有的独特优点,尤其是单体及材料合成方法的多样性,易于在其骨架中引入特定的亲CO_2官能团、有机配体、金属催化中心等,为CO_2吸附、活化及资源化利用提供了新的契机.本文将概述近年来功能型MOPs材料在CO_2吸附及催化转化领域的研究进展.涉及的MOPs主要为通过化学方法直接合成的、亲CO_2基团(如偶氮键、Tr?ger碱、咔唑、三嗪基团、希夫碱、苯并咪唑和氟原子等)功能化的有机聚合物材料,它们在CO_2高效吸附、活化的基础上实现了CO_2的催化转化,合成高附加值化学产品,如甲酸、甲基胺、有机碳酸酯等.

CO_2 is a critical component of greenhouse gas and also an abundant C1 resource.CO_2 chemistry has attracted more and more attention from the scientific community thanks to global warming.The unique advantages of microporous organic polymers（MOPs）,especially the diverse monomers and synthetic routes,easy to introduce specific CO_2-philic functionalities,organic ligands and metal catalytic center within the skeleton,have provided new opportunity for CO_2 capture,activation and utilization.This review will outline the recent research progress on CO_2 adsorption and catalytic conversion by functionalized MOP materials.The MOPs invovled are mainly those functionalized by CO_2-philic groups（e.g.azo,Troger＇s base,carbazole,triazine,Schiff base,benzimidazole and fluorine atoms） and synthesized directly through chemical coupling reactions,which could realize efficient capture,activation and the subsequent catalytic conversion of CO_2,to produce value-added chemicals such as formic acid,methyl amines and organic carbonates.
