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.

一种用于制氢反应的FeP粉末电催化剂

Petaloid FeP粉末是一种在酸性和碱性电解液中用于电化学制氢反应(HER)的高效且坚固的催化剂。花瓣状结构中的晶须和缺陷可扩展表面积并避免颗粒聚集,因此可确保HER的高电化学活性和机械结构稳定性。具体地,其需要分别在酸性溶液和碱性溶液中在10mA cm -2下的110mV和185mV的过电势。这种粉末状的FeP催化剂在PEM水电解中很有前景。
