Abstract

Graphitic carbon nitride (g-C₃N₄) has been identified as a promising material for photocatalytic hydrogen (H₂) production, but it shows a low activity. Herein, g-C₃N₄ doped with a benzene ring (B–CN_x) was synthesized via a simple thermal polycondensation method, exhibits 5.4 times higher H₂ evolution rate than the pristine one, and achieves a high apparent quantum yield of 4.11% at 420 nm.
