• Flash Joule heating controllably enhances sp2-C domains in N-doped biomass carbon, improving edge defects and graphitization.
• The axial modulation of sp2-C domains tunes the electronic structure of pyridinic and graphitic N, boosting oxygen electrocatalysis.
• Optimized catalyst achieves outstanding Zn-air battery performance: over 1200-h cycle stability and 121 mW cm−2 peak power density.
• DFT simulations reveal the mechanism: sp2-C domains regulate local charge density, enhancing catalytic activity.
