Abstract

Hydrogen is considered as sustainable and environmentally friendly energy for global energy demands in the future. Here a Co-FeS₂ catalyst with surface phosphide doping (P/Co-FeS₂ ) for hydrogen evolution reaction (HER) in acidic solutions is developed. The P/Co-FeS₂ exhibits superior HER electrochemical performance with overpotential of -90 mV at 100 mA cm^-2 and Tafel slope of 41 mV/decade and excellent durability.

Keywords: catalysts; earth abundant; hydrogen evolution reaction; iron pyrite; phosphide.
