Constructing high‐efficient, low‐cost and robust oxygen electrocatalysts toward rechargeable Zn–air batteries remains a big challenge. Herein, metallic Ni 3 Fe alloy nanoparticles encapsulated in 3D porous N‐doped graphene aerogel was prepared through a facile hydrothermal assembly and calcination process. Inspired by the unique configuration and strong electronic interactions between Ni 3 Fe and N‐doped graphene, Ni 3 Fe‐GA 1 exhibited outstanding activity and stability for OER, ORR, and Zn–air batteries.
