Graphitic carbon nitride (g-C₃N₄) nanosheet photocatalysts were synthesized via a facile impregnation-thermal method. The as-prepared materials were characterized and investigated as metal-free photocatalysts for the degradation of phenol in aqueous solution under visible light. Results revealed that the g-C₃N₄ nanosheets exhibited a 78.9% degradation for phenol after 30 min, which was much faster than that of the pristine g-C₃N₄. Using Brunauer-Emmett-Teller theory, the surface area of g-C₃N₄ nanosheets was 103.24 m²/g, which was much larger than that of g-C₃N₄. The larger surface area increases the contact area of the material with phenol, enhancing the photocatalytic activity. These results highlight the potential application of sustainable metal-free photocatalysts in water purification.
