Donor–acceptor covalent organic framework/g-C3N4 hybrids for efficient visible light photocatalytic H2 production

A donor–acceptor type covalent organic framework (COF) was used to construct TBTA/g-C₃N₄ hybrids for photocatalytic H₂ evolution. Under visible light irradiation, the hybrids exhibited an optimized H₂ evolution rate of 11.73 mmol g⁻¹ h⁻¹ without Pt.
