title: Chemical etching of manganese oxides for electrocatalytic oxygen reduction reaction.
abstract: Mixed-valent MnO(x) (1 < x < 2) was selectively synthesized by chemically etching MnO and Mn2O3 with ceric ammonium nitrate. The obtained MnO(x) exhibited greatly enhanced electrocatalytic activity toward the oxygen reduction reaction (ORR) as compared to the corresponding pristine oxides.
