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.
