A noble metal‐free Mn 2 O 3 catalyst with porous structure exhibits activity in the oxygen reduction reaction that is comparable to a commercial Pt/C catalyst (20% Pt loading) and, notably, higher than those of other Mn‐based oxides, such as Mn 3 O 4 and MnO 2 , as well as superior stability. In light of the low cost and high earth abundance of Mn, the highly active Mn 2 O 3 is a promising candidate to be used as a cathode material in metal‐air batteries and alkaline fuel cells.
