Noble metal-free NiS/P-S codoped g-C3N4 photocatalysts with strong visible light absorbance and enhanced H2 evolution activity

Noble metal-free NiS/PSCN exhibit 1.9 times visible light photocatalytic H2 evolution activity as that of NiS/CN result from the codoping effect of P-S for enhancing the visible light absorption and charge separation efficiency.119
