Carbon supported MnOx-Co3O4 as cathode catalyst for oxygen reduction reaction in alkaline media

The electroreduction of oxygen of MnOx-Co3O4/C was firstly studied in alkaline media. The MnOx-Co3O4/C showed better electrocatalytic activity towards ORR than MnOx/C and Co3O4/C. Compared to Pt/C, MnOx-Co3O4/C showed better methanol tolerance and durability in alkaline solution. Thus, the MnOx-Co3O4/C catalyst had potential for applications in metal-air batteries and alkaline fuel cells.
