 Abstract: Same selectivity hides different pathways: The same apparent 4-electron process for the oxygen-reduction-reaction hides different pathways over carbon-supported cobalt oxide catalysts depending on the potential. At low overpotentials, the ORR intermediate HO2− preferably disproportionates to oxygen, whereas at high overpotentials the disproportionation and reduction reaction occur in parallel.
