While Co(Sal) has only a 3% Faradaic yield for H<inf>2</inf>O formation, under the same conditions, the Faradaic yield for H<inf>2</inf>O formation is 80% with Co(Sal-H<inf>2</inf>Q).falseaerobic oxidation | cobalt | electrocatalysis | electron−proton transfer mediator | oxygen reduction reactionArticle2155543512643-126476 October 20235arJournal5WOS:001067295100001
