For the first time, cobalt particles were electrodeposited on the surface of manganese oxides by cyclic voltammetry (CV) from an aqueous solution of 0.1 M Na 2 SO 4 containing 5 mM CoSO 4 , and then the samples obtained were characterized by scanning electron microscopy (SEM) and energy dispersive X‐ray analysis (EDAX), respectively. And then, the as‐prepared Co/MnO 2 ‐coated graphite electrode was employed to the oxygen reduction reaction (ORR). Interestingly, the reduction peak potential of ORR on a Co/MnO 2 ‐modified graphite electrode was positively shifted for about 100 mV as compared with that on a MnO 2 ‐modified graphite electrode, indicating that the electrocatalysis of Co/MnO 2 composite towards ORR is superior to that of pure MnO 2 .
