Abstract: Graphene oxide and reduced graphene oxide have been chemically synthesized from multiwall carbon nanotubes. Using a proper oxidant, nanotubes can be “unzipped” longitudinally to form graphene oxide nanoribbons. Afterward, reduced graphene oxide can be obtained with the help of a reductant. Standard redox potentials of carbon are used for the selection of an oxidant and a reductant. Various physico-chemical methods are applied to verify the production of graphene-like materials. The synthesized products are used as a material for oxygen electrodes in fuel elements. The electrochemical characteristics of electrodes fabricated from graphenebased materials are found to depend on the redox ability of applied reagents. The obtained materials are shown to be promising catalyst carriers for electrodes in chemical current sources.
Key words: graphene oxide, reduced graphene oxide, electrocatalysis, electrode materials for oxygen electrode.
