We show that the first electron is transferred into O₂ molecules at the outer Helmholtz plane (ET-OHP) in oxygen reduction reaction. Based on the ET-OHP mechanism, location of the electrode potential dominantly characterizes the ORR activity, and it can be elevated by reducing the graphene size and/or including metal impurities.
