摘　　要：共价有机骨架材料(COFs)作为一类新型的纳米多孔晶体材料,由于具有表面积大、结构多样性、永久孔隙率高和热稳定性高等优点,在CO_2捕获性能方面表现出优异的应用前景。简要介绍了COFs的合成及表征方法、描述CO_2捕获性能的物理量。综述了几类COFs对CO_2捕获性能的研究进展,如含硼类、三嗪类和亚胺类COFs,并对它们的捕获性能进行了比较和总结,指出其优点和局限性。最后对未来的研究方向和发展趋势进行了展望。The increase of carbon dioxide(CO2)concentration in the atmosphere has caused a series of environmental problems in recent years.Carbon capture and sequestration(CCS)has been proposed to alleviate its concentration.Covalent organic frameworks(COFs)possess many fascinating features,such as large surface area,structural diversity,high permanent porosity,high thermal stability and so on,which enables COFs potential and important applications in CO2 capture from the mixed gases.The synthesis and characterization of COFs,physical quantities describing CO2 capture performance and theoretical methods for studying CO2 performance were briefly introduced.Research progresses of several kinds of COFs on CO2 capture were reviewed in detail,including boronbased,triazine-based and imine-based COFs.Their CO2 capture performances were compared,the advantages and limitations were summarized.Finally,aperspective in the field of COFs for CO2 capture was pointed out.
