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.
