Abstract: Covalent triazine frameworks(CTFs) as a new type of porous organic polymers(POPs) with nitrogen-rich content, high chemical stability, visible light sensitive, metal-free and fully conjugated structure, have gained considerable attention in the last ten years owing to their great potential in extensive applications, especially for photocatalysis systems. In this review, we propose to provide current progress in the design and synthesis of CTFs, along with an emphasis on their photocatalytic applications. Firstly, a brief background including the development of photocatalytic areas is provided. Then, synthetic strategies of CTFs are described and compared. Furthermore, the evolution of CTF materials in photocatalysis fields and strategies for enhancing photocatalytic performance is presented. Finally, some perspectives and challenges on synthesizing high crystalline CTFs and designing excellent catalytic performance of CTF materials are discussed, inspiring the development of CTF materials in photocatalytic applications.
