Improving Hydrogen Evolution Activity of Earth‐Abundant Cobalt‐Doped Iron Pyrite Catalysts by Surface Modification with Phosphide

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 electrochem...

Summary: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.
