Noble-metal-free NiS/C3N4 for efficient photocatalytic hydrogen evolution from water

A NiS/C3N4 photocatalyst containing earth-abundant elements only was constructed by means of a simple hydrothermal method. This photocatalyst shows efficient hydrogen evolution (48.2 μmol h−1) under visible light when using triethanolamine as a sacrificial reagent. The optimal loading of 1.1 wt % Ni...
