Facile transformation of low cost thiourea into nitrogen-rich graphitic carbon nitride nanocatalyst with high visible light photocatalytic performance

Polymeric nitrogen-rich graphitic carbon nitride (g-C3N4-T) nanocatalyst was synthesized for the first time with a facile approach by directly treating low cost thiourea in air. The g-C3N4-T demonstrated much higher visible light photocatalytic activity than that of g-C3N4 obtained from toxic dicyandiamide, C-doped TiO2 and P25.
