In this work, reduced graphene oxide-wrapped alpha-Mn2O3/alpha-MnO2 nanowires were prepared by heat treating (450 degrees C) of hydrothermally produced sample. XRD patterns confirmed the formation of alpha-Mn2O3 and alpha-MnO2 mixed phase. FE-SEM revealed the formation of nanowires with the average diameter, 38 nm. The rGO wrapping on the nanowires was confirmed by TEM. The presence of Mn3+ and Mn4+ species in the catalyst was confirmed in Raman and XPS analysis. The rGO-wrapped nanowires with high surface area (45.30 m(2) g(-1)) show better electrocatalytic reduction performance in alkaline medium. The rGO-wrapped alpha-Mn2O3/alpha-MnO2 catalyst exhibits a positive onset potential, + 0.79 V and nearly 4-electron transfer pathway for ORR.
