Abstract

N-doped WO₃ anchored on porous carbon (N–WO₃/PNC) was synthesized as an efficient oxygen reduction catalyst. The N doping reduced the overpotential of WO₃ during oxygen reduction. N–WO₃/PNC displayed a half-wave potential of 0.85 V. An N–WO₃/PNC-based zinc–air battery displayed a high power density of 209.7 mW cm⁻².
