CoMn2O4 embedded in MnOOH nanorods as a bifunctional catalyst for oxygen reduction and oxygen evolution reactions

CoMn₂O₄ embedded in MnOOH nanorods (CoMn₂O₄–MnOOH NRs) was prepared using a two-step hydrothermal method involving the oxidation of Mn by Co species in preformed MnOOH NRs, and the as-prepared catalyst exhibits an expectably remarkable performance for the ORR and the OER.
