Template-free synthesis of nanocage-like g-C₃N₄ with high surface area and nitrogen defects for enhanced photocatalytic H₂ activity

Abstract

Nanocage-like 3D porous graphitic carbon nitride (g-C₃N₄) with a high surface area and nitrogen defects was successfully prepared <italic>via</italic> a novel, template-free, cost-effective and hydrothermal-copolymerization route.
