Abstract

We synthesized a novel mesoporous Mn₂O₃ nanostructure as an electrocatalyst support, then Pd–Mn₂O₃ with different Pd loading amounts were obtained by a facile solvothermal method. The Pd–Mn₂O₃ demonstrated a good competitive ORR activity and a high selectivity in alkaline medium, which can be comparable to commercial Pt/C catalysts.
