Abstract Zinc‐air batteries (ZABs) have the advantages of high energy density and rich zinc raw materials. It is a low‐cost, green sustainable storage device. At present, one key technologies that hinder large‐scale application ZABs design fabrication oxygen evolution reaction (OER) reduction (ORR) bifunctional catalysts with excellent performance, especially non‐platinum‐based catalysts. Here N‐doped carbon‐coated Fe‐based selenium oxide catalyst Fe 2 O(SeO 3 ) /Fe C@NC performance has been fabricated by one‐step pyrolysis then electrochemical oxidization. The experimental results confirmed existence Fe−O−Se bonds in crystal phase C@NC, could obviously enhance ORR OER catalytic C@NC. Density functional theoretical calculations (DFT) had higher d ‐band center atom lower p ‐orbital coupling degree its own lattice O than , which leads to site being more likely adsorb external intermediates. modification coordination environment atoms optimizes adsorption for Compared showed obvious enhancements ORR/OER activities half‐wave potential 0.91 V 0.1 M KOH electrolyte low overpotential 345 mV at 10 mA cm −2 1.0 electrolyte. peak power specific capacity C@NC‐based are those Pt/C+RuO ‐ZABs. above demonstrate asymmetrical plays role improving ZABs.
