Accelerating the oxygen reduction reaction (ORR) is a main subject of electrocatalysis research. A key ORR step involves creating a hydroperoxyl functional group (OOH*) intermediate. This study examines the defect influence on the formation of the OOH* in a zirconia-based cathode during hydroxyl gro...
