Graphene oxide (GO) cast on conductive substrates was electrochemically reduced in some organic solvents. The amount of electricity required for the almost complete reduction of GO was 2.0C for 1 mg GO, corresponding to attaching of a one-electron reducible species to each benzene ring in graphene. The electrochemically reduced GO film gave an electrical conductivity of about 3 S cm(-1) and exhibited a relatively high specific capacitance of 147.2 F g(-1) in propylene carbonate. The electrochemical reduction of GO was feasible on Al foils as well. (C) 2011 Elsevier Ltd. All rights reserved.
