摘要Defects have a vital effect on the band structures and properties of semiconductor photocatalysts. Herein, we developed a one-step strategy to introduce defects in the framework of g-C3N4 by controllable copolymerization of melamine with a series of partially reactive end capped monomers. The capping molecules have great impacts on the properties of modified g-C3N4. The obtained defective g-C3N4 exhibits an increased surface area, improved charge carrier separation efficiency, and a narrowed band gap with a negative shift of the conduction band. Particularly, defect-rich CN-DPT shows 10 times improvement of visible light activity for hydrogen production compared with pristine g-C3N4.
