The photoassisted treatment not only helps to create abundant holes, endowing g-C₃ N₄ with more exposed catalytic active sites and crossplane diffusion channels to shorten the diffusion distance of both reactants from the surface to bulk and charge carriers from the bulk to surface, but also introduces nitrogen vacancies in the tri-s-triazine repeating units of g-C₃ N₄ , inducing the narrowing of intrinsic bandgap and the formation of defect states within bandgap to extend the visible-light absorption range and suppress the radiative electron-hole recombination. As a result, the holey defective g-C₃ N₄ photocatalysts show much higher photocatalytic activity for H₂ O₂ production with optimized enhancement up to ten times higher than pristine bulk g-C₃ N₄ . The newly developed synthetic strategy adopted here enables the sufficient utilization of solar energy and shows rather promising for the modification of other materials for efficient energy-related applications.
