Insight into photocatalytic activity, universality and mechanism of copper/chlorine surface dual-doped graphitic carbon nitride for degrading various organic pollutants in water.

A new Cu/Cl-g-C3N4 photocatalyst is prepared and surface dual-doped effect of Cu/Cl elements on g-C3N4 extends visible light harvest range, elevates CB potential and improves the separation efficiency of charge carriers.
