Methods to synthesize crystalline covalent triazine frameworks (CTFs) are limited and little attention has been paid to development of hydrophilic CTFs and photocatalytic overall water splitting. A route to synthesize crystalline and hydrophilic CTF-HUST-A1 with a benzylamine-functionalized monomer is presented. The base reagent used plays an important role in the enhancement of crystallinity and hydrophilicity. CTF-HUST-A1 exhibits good crystallinity, excellent hydrophilicity, and excellent photocatalytic activity in sacrificial photocatalytic hydrogen evolution (hydrogen evolution rate up to 9200 mu mol g(-1) h(-1)). Photocatalytic overall water splitting is achieved by depositing dual co-catalysts in CTF-HUST-A1, with H-2 evolution and O-2 evolution rates of 25.4 mu mol g(-1) h(-1) and 12.9 mu mol g(-1) h(-1) in pure water without using sacrificial agent.
