Mn-Co containing spinel oxides are promising, low-cost electrocatalysts for the oxygen reduction reaction (ORR). Most studies are devoted to the design of porous Mn-Co spinels or to strongly coupled hybrids (e.g., MnCo2 O4 /N-doped-rmGO) to maximize the mass efficiency. The lack of analyses by metal...
