The low-cost cobalt nanoparticles were deposited on the channels of carbon nitride nanotubes (C₃N₄ NTs) by a chemical reduction process. The morphology and structures of the synthesized Co/C₃N₄ NTs nanocomposite were analyzed by comprehensive characterization methods. The effects of Co loading content on the visible-light-induced photocatalytic hydrogen production rate were studied. Our results show that this metal-semiconductor heterojunction effectively enhances the separation of photogenerated electron-holes. After 2 h of visible light irradiation, the optimal hydrogen production was obtained when the Co loading was 5%(w/w), and the hydrogen production rate was 1.7 times that of pure C₃N₄ NTs.
