摘要

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.
