WitrynaAbstract. Oxygen reduction reaction (ORR) is one of the most important electrochemical reactions. Starting from a common reaction intermediate *-O-OH, the ORR splits into two pathways, either producing hydrogen peroxide (H 2 O 2) by breaking the *-O bond or leading to water formation by breaking the O-OH bond. However, it is puzzling why …
