title: Noble-metal-free NiS/C3 N4 for efficient photocatalytic hydrogen evolution from water.
abstract: A NiS/C3 N4 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 % NiS on C3 N4 as a cocatalyst can enhance the H2 production by about 250 times compared with the native C3 N4 . The highest apparent quantum efficiency of 1.9 % was recorded at 440 nm.
