A hierarchically functionalized hybrid electrode for Zn–air batteries is discussed that requires no carbon. Instead, an oxygen evolution reaction (OER)‐active, porous, conductive, and corrosion‐resistant nitride Ni₃FeN is used as a support for oxygen reduction reaction (ORR)‐active ordered intermetallic Fe₃Pt NPs. The porosity in the Ni₃FeN substrate is an important enabling factor for the high OER activity.

通过无碳分级官能化制备的活性且功能强大的双功能氧电催化剂

讨论了一种无需碳的用于锌-空气电池的功能化混合电极。取而代之的是，使用氧释放反应（OER）活性，多孔，导电和耐腐蚀的氮化物Ni ₃ FeN作为氧还原反应（ORR）活性有序金属间Fe ₃ Pt NP的载体。Ni ₃ FeN基体中的孔隙率是实现高OER活性的重要因素。
