An ecofriendly chemical reduction of graphene oxide (GO) in water is reported. The reducing agent is an electrochemically reduced Keggin-type polyoxometalate (SiW12O405−). Moreover, this process leads to the fabrication of SiW12@rGO nanocomposite. This nanohybrid exhibits an electrochemical response which combines high faradic and capacitive currents due to high coverage of polyoxometalates on the rGO sheets. Therefore this material has strong potentiality for energy storage.
