Synthesis and Electrocatalytic Properties of Materials Based On Graphene Structures

Catalysts for oxygen electrodes based on graphene structures have been obtained

by the chemical synthesis. Oxidizing and reducing agents were selected on the basis

of their standard redox potentials. For the obtained materials, the morphology, physical

and chemical properties, and electrocatalytic activity for the reaction of oxygen reduction

have been investigated. It was shown that the synthesized graphene oxide and reduced

graphene oxide are promising catalyst carriers for the oxygen electrode of fuel cells,

which can replace commercial electrode materials containing platinum. The specific

capacity of the electrode based on the developed materials was about 500 mAh g-1 at

200 mV polarization. The synthesized materials are stable and catalytically active
