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