AbstractSustainable hydrogen generation via electrocatalytic/photocatalytic water splitting has been widely regarded as the most promising energy carrier and has attracted extensive attention. However, a considerable hydrogen evolution reaction (HER) always involves the rare noble metals. Herein, we report a new HER candidate, an Fe-doped NiS2 (Fe-NiS2) nanosheet, with the performance of high activity and electrochemical stability. We chose the sulfidation of Ni(OH)(2) under mild calcinated temperature for Fe-NiS2 formation. The theoretical and experimental results suggest that the Fe3+ doping into the surface lattice of the NiS2 (002) facet lowers the activation energy of H-2 generation. The synthesized Fe-NiS2 sample shows good electrocatalytic HER performance with a low Tafel slope of 37 mV dec(-1) and a small overpotential of 121 mV at 10 mA cm(-2). Moreover, Fe-NiS2 gives considerable stability with a negligible loss of HER value l after a reaction of 1100 min. The Fe-NiS2 sample is also in situ loaded onto the surface of CdS nanorods to act as a co-catalyst for photocatalytic H-2 generation with the result of 3.2 mmol h(-1) g(-1) hydrogen evolution under visible light, 46 times higher than with bare CdS. This work can help us to design new electrocatalysts for water splitting; it also provides a good understanding of the hydrogen evolution pathway.
