The Bipolar Mode of One‐Step Plasma Electrochemical Synthesis of Few Layer Graphene Structures Decorated with Transition Metal Oxides

Abstract

We present the method of conjugated bipolar plasma electrochemical synthesis of aqueous suspensions of composites of few‐layer graphene structures with Co3O4 and Mn3O4 oxides and creation of mixed electrocatalysts based on them. As shown by the rotating disk electrode method, the best catalytic activity towards oxygen reduction reaction exceeding that for each individual component is demonstrated by the composition containing equal amounts of these composites.
