Petaloid FeP powder is an efficient and robust catalyst for electrochemical hydrogen evolution reaction ( HER) both in the acid and alkaline electrolyte. The whiskers and defects in the petaloid structure can extend the surface area and avoid particles aggregation, thus high electrochemical activity and mechanical structure stability are guaranteed for the HER. Specifically, it needs an overpotential of 110 mV and 185 mV at 10 mA cm(-2) in acid solution and alkaline solution respectively. This powder FeP catalyst is promising in PEM water electrolysis.
