摘要:
A NiS/C3N4 photocatalyst containing earth-abundant elements only was constructed by means of a simple hydrothermal method. This photocatalyst shows efficient hydrogen evolution (48.2molh(-1)) under visible light when using triethanolamine as a sacrificial reagent. The optimal loading of 1.1wt% NiS on C3N4 as a cocatalyst can enhance the H-2 production by about 250times compared with the native C3N4. The highest apparent quantum efficiency of 1.9% was recorded at 440nm.
