Reversible Electrical Reduction and Oxidation of Graphene Oxide [PDF]

ACS Nano, 2011
We demonstrate that graphene oxide can be reversibly reduced and oxidized using electrical stimulus. Controlled reduction and oxidation in two-terminal devices containing multilayer graphene oxide films are shown to result in switching between partially reduced graphene oxide and graphene, a process which modifies the electronic and optical properties.
