Abstract

A hybrid of holey graphene and Mn₃O₄ is prepared by a one-step process, in which the formation of a holey structure is accompanied with Mn₃O₄ nanoparticles through a high temperature reaction between graphene oxide sheets and KMnO₄. Holey graphene and Mn₃O₄ collaboratively attributed to the enhanced catalytic activity and efficiency towards the oxygen reduction reaction.
