Abstract The strategic regulation of the electronic properties and coordination environment single‐atom sites through integration metal nanoclusters emerges as a promising route to enhance oxygen reduction reaction (ORR) performance Fe–N–C materials. Here, catalyst (FeIn–NC) is successfully developed in which materials encapsulate Fe–In alloy nanoclusters, it shows excellent ORR activity durability under alkaline conditions, with high half‐wave potential 0.924 V (vs RHE) zinc–air battery power density 202.1 mW cm −2 , superior commercial Pt/C catalysts. Theoretical calculations unravel that synergistic interaction between FeN 4 site modifies structure charge distribution at site, thereby enhancing electrocatalytic ORR. Potential‐dependent microkinetic modeling (MKM) further discloses mechanisms on identified sites. This work provides viable strategy for improvement via p‐block metal‐based nanoclusters.

Abstract Stable, efficient, and economical bifunctional electrocatalysts for oxygen evolution reaction (OER) reduction (ORR) are needed rechargeable Zn–air batteries. In this study, a directional electron transfer pathway is exploited in spatial heterojunction of Co y Ni x @Fe─N─C heterogeneous catalyst effective electrolysis (OER/ORR). Thereinto, the Co/Ni alloy strongly coupled to Fe─N─C support through Co/Ni─N bonds. DFT calculations experimental findings confirm that bonds play bridging role from support, increasing content pyridinic nitrogen ORR‐active support. addition, discovered mechanism enhances both ORR/OER activity durability catalyst. The 0.66 0.34 with optimal Ni/Co ratio exhibits satisfying electrocatalytic performance, requiring an ORR half‐wave potential 0.90 V OER overpotential 317 mV at 10 mA cm −2 alkaline electrolytes. assembled zinc–air batteries (ZABs) incorporating cathode charge–discharge voltage gap comparable Pt/C||IrO 2 assembly high robustness over 60 h 20 .
