| Abstract: | The electroreduction of oxygen was firstly studied on Ag/Co3O4–C in alkaline media prepared by depositing Ag on Co3O4 modified carbon (Co3O4–C). The Ag/Co3O4–C composite not only displayed relatively large electrochemical active surface area (ESA), high catalytic activity towards oxygen reduction reaction (ORR), but also exhibited good methanol tolerance and stability in alkaline media. Ag/Co3O4–C could be a valuable catalyst for ORR and be applied to alkaline fuel cells and metal–air batteries. |
