Abstract

Abstract: An ecofriendly chemical reduction of graphene oxide (GO) in water is reported. The reducing agent is an electrochemically reduced Keggin‐type polyoxometalate (SiW12 O40 5− ). 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. Abstract : Highly decorated : Graphene oxide and partly reduced silicotungstic polyanions can be mixed to form a hybrid nanocomposite made of reduced graphene oxide decorated with electroactive inorganic clusters, tungsten polyoxometalates (see figure). The nanohybrid exhibits excellent electrochemical properties, combining faradic and capacitive responses.
