Abstract

A NiS/C₃N₄ photocatalyst containing earth-abundant elements only was constructed by means of a simple hydrothermal method. This photocatalyst shows efficient hydrogen evolution (48.2μmol h^-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 H₂ production by about 250times compared with the native C₃N₄. The highest apparent quantum efficiency of 1.9 % was recorded at 440nm. The fall of the nobility: Noble-metal-free NiS/C ₃N₄ was synthesized by means of a simple hydrothermal method. A small percentage of NiS loading enhances H₂ evolution compared to the native C₃N₄. In addition, a higher apparent quantum efficiency is recorded. The appropriate loading of NiS makes C₃N₄ a stable and low-cost photocatalyst system for H ₂ evolution.
