text: Mn3O4@CoMn2O4 nanoparticles (NPs) were produced at low temperature and ambient
atmosphere using a one-pot two-step synthesis protocol involving the cation exchange
of Mn by Co in preformed Mn3O4 NPs. Selecting the proper cobalt precursor, the
nucleation of CoxOy crystallites at the Mn3O4@CoMn2O4 surface could be simultaneously
promoted to form Mn3O4@CoMn2O4–CoxOy NPs. Such heterostructured NPs were investigated
for oxygen reduction and evolution reactions (ORR, OER) in alkaline solution.
Mn3O4@CoMn2O4–CoxOy NPs with [Co]/[Mn] = 1 showed low overpotentials of 0.31 V
at −3 mA·cm–2 and a small Tafel slope of 52 mV·dec–1 for ORR, and overpotentials
of 0.31 V at 10 mA·cm–2 and a Tafel slope of 81 mV·dec–1 for OER, thus outperforming
commercial Pt-, IrO2-based and previously reported transition metal oxides. This
cation-exchange-based synthesis protocol opens up a new approach to design novel
heterostructured NPs as efficient nonprecious metal bifunctional oxygen catalysts.
