Abstract
We electrochemically reduce graphene oxide to control the oxygen functional species. The electrocatalytic activities toward L-ascorbic acid oxidation of as-received and electroreduced graphene oxides are compared by cyclic voltammetry and surface changes by XPS and XRD analysis. The observations represent that edge-like oxygen functional groups by optimal electrochemical reduction result in the higher electrocatalytic activity.
Research highlights► Electrocatalysis of graphene oxide in Vitamin-C (L-AA) oxidation. ► Controlling of oxygen species onto graphene oxide. ► Clarification of the functionality of reactive graphene surface.
