The electrochemical oxygen reduction reaction (ORR) mechanism was generally considered to be O₂→ OOH∗→ O∗→ OH∗→ H₂O (O∗ mechanism). This O∗ mechanism predicted reasonable ORR half-wave potential (E1/2) of Co/N/C but abnormally underestimated the one of Fe/N/C. Herein, we highlight an unconventional...
