Abstract

Porous g-C₃N₄ was synthesized by a facile template-free method to control the reaction of polymer according to Le Chatelier's principle. The resulting porous g-C₃N₄ material has high Brunauer–Emmett–Teller (BET) surface area (201–209 m² g⁻¹) and large pore volume (0.50–0.52 m³ g⁻¹), and shows a ten times enhanced photocatalytic activity for methyl orange (MO) photodegradation under visible light (λ > 420 nm) irradiation.
