title: Improving Hydrogen Evolution Activity of Earth-Abundant Cobalt-Doped Iron Pyrite Catalysts by Surface Modification with Phosphide.
abstract: Hydrogen is considered as sustainable and environmentally friendly energy for global energy demands in the future. Here a Co-FeS2catalyst with surface phosphide doping (P/Co-FeS2) for hydrogen evolution reaction (HER) in acidic solutions is developed. The P/Co-FeS2exhibits superior HER electrochemical performance with overpotential of -90 mV at 100 mA cm-2and Tafel slope of 41 mV/decade and excellent durability.
