The continuing increase of the concentration of atmospheric CO₂ has caused many environmental issues including climate change. Catalytic conversion of CO₂ using thermochemical, electrochemical, and photochemical methods is a potential technique to decrease the CO₂ concentration and simultaneously obtain value-added chemicals. Due to the high energy barrier of CO₂ however, this method is still far from large-scale applications which requires high activity, selectivity, and stability. Therefore, development of efficient catalysts to convert CO₂ to different products is urgent. With their well-engineered pores and chemical compositions, high surface area, elevated CO₂ adsorption capability, and adjustable active sites, porous crystalline frameworks including metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) are potential materials for catalytic CO₂ conversion. Here, we summarize our recent work on MOFs and COFs for thermocatalytic, electrocatalytic, and photocatalytic CO₂ conversion and describe the structure–activity relationships that could guide the design of effective catalysts.
