Abstract Zinc–air batteries (ZABs) hold potential as clean, cost‐effective, and sustainable energy storage system for the next generation. However, application of ZABs remains challenging because their poor rechargeability low efficiency . The design efficient bifunctional catalysts toward oxygen reduction reaction (ORR) during discharging evolution (OER) charging is essential to developing rechargeable ZABs. Transition metal (TM)‐doped carbon (TM‐C) materials stand out from all available due excellent specific surface area, diverse morphological structures , multiple active sites formed after TM doping. This paper, therefore, focuses on synthesis, electrochemical properties, mechanism TM‐C catalysts. To make a novelty logical statement, voltage difference (Δ E = i 10 − 1/2 ) between ORR/OER catalytic process employed categorize different reported in recent years, which are divided into two groups: I 0.7 0.9 V) II 0.5 V). mechanisms clarified. More ways ideas synthesizing high‐performance also provided. Finally, current problem prospects this group presented.

Abstract Cobalt–nitrogen–carbon is hitherto considered as one of the most satisfactory alternatives to precious metal catalysts for oxygen electrocatalysts. However, precisely tuning local coordination Co sites and thus engineering d‐orbital electron configuration optimize binding energy intermediates remains a huge challenge. Herein, robust electrostatic self‐assembly strategy developed engineer penta‐coordinated by introducing axial O ligands with atomic‐level precision form CoN 4 1 configurations on MXene nanosheets (CoN ‐O/MX). The optimized ‐O/MX demonstrates outstanding bifunctional electrocatalytic performance small potential gap 0.72 V, significantly outperforming cobalt–nitrogen–carbon catalyst plane‐symmetric counterparts. Zn–air batteries integrated provide an peak power density 182.8 mW cm −2 long‐term cyclability 250 h. Density functional theory calculations reveal that CoO induces electronic delocalization draw off partial electrons from dz 2 orbital, which forms unsaturated orbital filling lifts level, resulting in stronger Lewis basicity facilitate injection into intermediate. study presented here provides not only novel methodology achieve precise control heteroatom coordination, but also fundamental understanding about structure–activity relationships d z2 orbitals.
