摘要：
Manganese oxides/graphene composite were synthesized by the reflux-calcination method. The catalyst composed of 48 wt.% Manganese oxides nanoparticles were distributed evenly on graphene sheets, which was used as cathode catalyst for the oxygen reduction reaction in a 6 M KOH solution. The mesoporous structure showed high electrochemical activation, in which the oxygen reduction potential reached -0.29 V vs. Hg/HgO. Calculations suggested that it possessed good electrocatalytic activity toward the two-electron reduction of oxygen.
