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.

Significant research has focused on cost–effective, highly active, and exceptionally stable non–noble metal electrocatalysts (NNMEs) to boost the performance of oxygen reduction reaction (ORR). Of note, development design synthesis Fe–N–C is essential but remains challenging. Herein, Fe N co–doped porous carbon material with a yolk–shell (YS) structure, termed SA–H2TPyP@PDA–Fe (900), was fabricated by self–assembly metal–free porphyrin as yolk polymerization dopamine shell an addition iron salts, followed high–temperature pyrolysis acid–leaching. As result, active sites, like FeN4 N–doped C, within rich YS structures, play important role for ORR in alkaline media. The (900) electrocatalyst shows positive performances than those SA–H2TPyP SA–H2TPyP@PDA indicating dominating function structure decorated Fe–based species. This efficient route template–free–induced preparation discovers NNMEs ORR.
