Heterointerface Engineering of FeOOH@Ni3N Electrocatalysts for Industrially Compatible Alkaline Water Electrolysis

open access: yesSmall, EarlyView.
A hierarchically structured FeOOH@Ni3N electrocatalyst supported on Ni foam enables high‐rate alkaline water electrolysis with industrial‐level stability. Operando spectroscopy reveals that the Fe–Ni heterointerface stabilizes high‐valent Ni4+ = O/Fe4+ = O species and promotes a hydroxyl nucleophilic attack (HNA) mechanism, wherein OH− attack on ...
