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 2.0 C 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.
