Solvothermal synthesis of covalent triazine framework and its application in photodegradation of organic dyes

Abstract Covalent triazine frameworks (CTFs) have recently attracted increasing attention in various fields. However, it is still challenging to prepare CTFs with good crystallinity via an efficient approach under mild conditions. This work offered a useful protocol based on a homogeneous solvothermal monomer/catalyst/solvent system for the preparation of crystalline CTFs, directly from several nitrile-containing monomers. The synthesized CTFs were featured with good crystallinity and high thermal stability. Finally, an afforded CTF material was applied as a photocatalyst for the degradation of Rhodamine B with excellent performance. Meanwhile, the CTF material was found to be chemically stable after the photocatalytic reaction.
