Abstract N‐doped carbon confined alloy catalysts possess considerable potential in facilitating oxygen electrocatalytic reaction and consequent applications metal air batteries, but the sluggish catalytic kinetics high barrier of reduction (ORR) remain bottleneck restricting its further development. Here, a novel CoFe‐NiFe biphase nanoheterojunction encapsulated within nanotubes (CoFe‐NiFe@NCNT) is fabricated via hydrothermal carbothermic approach. Owing to plentiful active sites electrical conductance, difference between OER ORR amounts merely 0.68 V. Simultaneously, performance Zn‐air Mg‐air batteries assembled by CoFe‐NiFe@NCNT serving as air‐cathode are superior that commercial Pt/C + RuO 2 . The DFT outcomes reveal transformation *OOH *O rate‐determining step (RDS) ORR/OER. Also, synergy heterojunction conducive reduce energy barrier. This study offers profound understanding toward structural design electrocatalysts utilization metal‐air for portable wearable electronic apparatuses.
