Abstract
Abstract Converting carbon dioxide (CO 2 ) into fuel and high‐value‐added chemicals is considered a green and effective way to solve global energy and environmental problems. Covalent triazine frameworks (CTFs) are extensively utilized as an emerging catalyst for photo/electrocatalytic CO 2 reduction reaction (CO 2 RR) recently recognized for their distinctive qualities, including excellent thermal and chemical stability, π‐conjugated structure, rich nitrogen content, and a strong affinity for CO 2 , etc. Nevertheless, single‐component CTFs have the problems of accelerated recombination of photoexcited electron‐hole pairs and restricted conductivity, which limit their application for photo/electrocatalytic CO 2 RR. Therefore, emphasis will then summarize the strategies for enhancing the photocatalytic and electrocatalytic efficiency of CTFs for CO 2 RR in this paper, including atom doping, constructing a heterojunction structure, etc. This review first illustrates the synthesis strategies of CTFs and the advantages of CTFs in the field of photo/electrocatalytic CO 2 RR. Subsequently, the mechanism of CTF‐based materials in photo/electrocatalytic CO 2 RR is described. Lastly, the challenges and future prospects of CTFs in photo/electrocatalytic CO 2 RR are addressed, which offers a fresh perspective for the future development of CTFs in photo/electrocatalytic CO 2 RR.
