Oxygen‐doped carbon materials show great promise to catalyze two‐electron oxygen reduction reaction (2e‐ORR) for electrochemical synthesis of hydrogen peroxide (H2O2), but the identification of the active sites is the subject of ongoing debate. In this study, a tandem oxidation strategy is developed...
