Nanostructured silver nanowires-graphene hybrids for enhanced electrochemical detection of hydrogen peroxide

We report a facile one-step strategy to synthesize interconnected Ag nanowires (NWs)-graphene hybrids with excellent interfacial electron transfer ability for the electrochemical detection of hydrogen peroxide. The simple approach combines the advantages with individual components and also avoids the interface problem typically encountered in the multiple-step process. Moreover, we show that in the one-step process, the presence of graphene promotes the preferential growth of long NWs whereas the growth of Ag NWs prevents the aggregation of individual graphene sheets. Owing to the synergistic cooperation effects, the nanostructured Ag NWs-graphene hybrids exhibit enhanced detection performances compared with their single component counterpart.
