Abstract The integration of transition metal‐carbon composites has shown remarkable potential in achieving superior bifunctional electrocatalytic activity and robust stability rechargeable zinc‐air batteries (ZABs), primarily through electronic structure modulation strategic structural design. While significant research is dedicated to the initial performance electrocatalysts for ZABs, their dynamic evolution during charge–discharge cycling remains underexplored. In this study, CoFe nanoparticles are encapsulated within carbon nanotubes co‐doped with nitrogen phosphorus (NPC) mitigate dissolution erosion risks. Further, catalyst surface (CoFe‐NPC) precisely modified a thin layer nickel oxide (NiO) via atomic deposition (ALD), forming protective catalytic activity. resulting ALD‐modified catalyst, CoFe‐NPC@NiO, exhibits outstanding (Δ E = 0.592 V) oxygen reduction reaction (ORR) (OER). Notably, liquid flow ZAB using CoFe‐NPC@NiO cathode demonstrates exceptional (2700 h, ≈4 months). Theoretical calculations situ X‐ray absorption spectroscopy (XAS) analyses reveal that NiO modification significantly enhances both electrocatalyst. This work will provide valuable insights into design advanced electrocatalysts, facilitating advancements enhancement, improvement, selectivity optimization.

Regulating the surface oxophilicity of electrocatalyst is known as an efficient strategy to mitigate order-of-magnitude kinetic slowdown hydrogen electrocatalysis in a base, which great scientific and technological significance. So far, its mechanistic origin remains mainly ascribed bifunctional or electronic effects that revolve around catalyst-intermediate interactions under extensive debate.
