The development of high-performance bifunctional single-atom catalysts for use in applications, such as zinc–air batteries, is greatly impeded by mild oxygen reduction and evolution reactions (ORR OER). Herein, we report a electrocatalyst designed to overcome these limitations. catalyst consists well-dispersed low-nuclearity Co clusters adjacent single atoms over nitrogen-doped carbon matrix (CoSA+C/NC). precisely tailored asymmetric electronic structures are achieved with strong interactions between species. optimize the adsorption/desorption strength oxygenated intermediates on single-atomic sites endow exceptional activity under alkaline conditions half-wave potential (E1/2) 0.91 V an overpotential (η) 340 mV at 10 mA cm–2. In addition, battery assembled CoSA+C/NC achieves high power density 284.1 mW cm–2 long operational lifespan 400 h, superior those benchmark Pt/C + RuO2. Experimental findings theoretical analysis reveal that enhanced stems from synergistic sites. Consequently, overbinding *OH suppressed accelerated removal. This work establishes design principle advanced electrocatalysts multiphase metal species bearing interactions.

Abstract Seawater electrolyte‐based zinc‐air batteries (S‐ZABs) are considered the promising choice for highly efficient marine power supply, owing to their high specific energy, low cost, and eco‐friendliness. However, air‐cathode suffers from sluggish oxygen reduction reaction (ORR) kinetics together with severe adsorption of Cl − in seawater electrolytes, which severely limits service life efficiency S‐ZABs. Herein, precisely decorating axially coordinated ions (Cl ) on Fe atomic sites (Cl‐Fe SA /NC) construct a local negatively charged interface inhibit is proposed, exhibits desirable ORR activity, good stability almost no loss electrocatalytic performance after long‐term test. Moreover, assembled battery achieves peak density 208.0 mW cm −2 , 1.45 times higher than commercial Pt/C‐based Density functional theory calculations reveal that not only constructs corrosion poisoning active by but also regulates electronic states optimize adsorption/desorption energy intermates, thus improving activity Cl‐Fe /NC.
