摘要:

共价有机框架(COFs)是一类通过共价键连接的新兴材料,大部分具有高的热/化学稳定性(除硼酸类COFs)、永久的孔隙率、较大的比表面积和较好的结晶性。此外,COFs中的单体单元结构可调并且可以与许多过渡金属离子配位来提供催化活性位点,这一系列优势使得COFs有利于催化各种反应。其中,COFs对CO2还原反应(CO2RR)有着优异的催化作用。这主要是因为COFs可调控的孔结构使得它可以吸附大量CO2,而且COFs中的π-π堆积结构能促进电荷转移,可以大大提高CO2还原效率。COFs可作为光/电催化剂高效地将CO2还原为CO、CH4和HCOOH等多种产物。本综述讨论了由COFs催化的CO2RR的重要成果,包括光/电催化CO2RR和光电耦合CO2RR。此外,还对COFs作为CO2RR催化剂的未来发展进行了展望。

Abstract:

Covalent organic frameworks (COFs) are a class of emerging materials connected by covalent bonds, which have high thermal/chemical stability (except boric acid COFs), permanent porosity, large specific surface area and good crystallinity. In addition, the structure of the monomer unit in COFs is adjustable and can coordinate with many transition metal ions to provide catalytic active sites. These advantages make COFs helpful to catalyze various reactions. Among them, COFs have an excellent catalytic effect on the CO2 reduction reaction (CO2RR). This is mainly because the adjustable pore structure of COFs allows them to adsorb a large amount of CO2 and the π-π stacking structure in COFs can promote charge transfer, which can greatly improve the efficiency of CO2 reduction. COFs can be used as photo/electrocatalysts to efficiently reduce CO2 to CO, CH4, HCOOH and other products. This review discusses the important achievements of CO2RR catalyzed by COFs, including photo/electrocatalytic CO2RR and photoelectric coupling CO2RR. In addition, the future development of COFs as CO2RR catalysts is also prospected.
