Summary:Constructing high‐efficient, low‐cost and robust oxygen electrocatalysts toward rechargeable Zn–air batteries remains a big challenge. Herein, metallic Ni3Fe 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 Ni3Fe and N‐doped graphene, Ni3Fe‐GA1 exhibited outstanding activity and stability for OER, ORR, and Zn–air batteries.
