Cobalt-doped graphitic carbon nitride with enhanced peroxidase-like activity for wastewater treatment

The peroxidase-like activity of graphitic carbon nitride (g-C ₃ N ₄ ) is dramatically increased by a small cobalt doping. The cobalt-doped g-C ₃ N ₄ was used for wastewater treatment, exhibiting much higher degradation rate than that of pure g-C ₃ N ₄ .
