Electrochemical reduction of graphene oxide in organic solvents
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.
