Abstract Metal‐organic framework (MOF)–carbon composite materials are promising candidates for use as electrocatalysts in zinc‐air batteries (ZAB). Electrospun carbon nanofibers (CNFs) particularly advantageous conductive substrates due to their porous and binder‐free architecture. However, achieving stable efficient dispersion of MOFs on CNFs remains a significant challenge. In this study, we present the synthesis electrode comprising nickel‐based metal‐organic decorated over cobalt oxide‐embedded (NM@CCNF), designed self‐standing bifunctional electrocatalyst rechargeable ZABs. The NM@CCNF features unique open flower petal‐like morphology providing abundant active sites oxygen reduction (ORR) evolution reactions (OER). Electrochemical testing demonstrated that exhibited low potential gap (Δ E ) between ORR OER 0.794 V, surpassing individual noble metal catalysts rivaling benchmark Pt/C IrO₂ combinations. assembled ZAB high specific capacity 830 mA h g Zn −1 , peak power density 77.36 mW cm −2 . Long‐term cycling stability tests 200 cycles showed minimal voltage degradation, indicating excellent durability rechargeability. Post‐mortem analysis confirmed reversible formation ZnO during operation, validating battery's These findings highlight candidate next‐generation energy storage systems.

Atomically dispersed metal-nitrogen-carbon materials (AD-MNCs) are considered the most promising non-precious catalysts for oxygen reduction reaction (ORR), but it remains a major challenge simultaneously achieving high intrinsic activity, fast mass transport, and effective utilization of active sites within single catalyst. Here, an AD-MNCs consisting defect-rich Fe-N
