Heterogeneous catalytic conversion of carbon dioxide(CO2) into high value-added fine organic chemicals and chemical fuels has been indicated the important research value and industrial application potential. Due to their high specific surface area, ordered channel structure, excellent chemical and thermal stability, controllable catalytic sites, covalent organic frameworks(COFs) as an emerging class of organic materials, have exhibited outstanding advantages for adsorption and conversion of CO2. Specifically functional molecules or catalytic sites can be easily incorporated into the channel or surface of COFs by using rational strategy, which can efficiently and purposefully achieve the selective regulation for the specific reactions and provide a favorable microenvironment for substrates transport in reaction process. These merits thus can endow promising catalytic performance for heterogeneous catalysis, which greatly give rise to the rapid development and have a good application prospect for the catalytic conversion and utilization of CO2 over COFs catalysts. Therefore, this review briefly focuses on the advances of the conversion of CO2 into important fine chemicals and chemical fuels over COFs in recent years and proposes the key scientific issues involved in this field. Moreover, we also attempt to propose an outlook on the prospective developments for the CO2conversion and utilization by using COFs catalytic materials.
