The facile synthesis of the novel graphene/gold nanorods (GNs-AuNRs) nanocomposites was reported. The PVP was used not only as the dispersant of graphene but also to immobilize positively charge AuNRs. The electrode modified with the PVP-GNs-AuNRs composite showed prominent electrocatalytic activity toward the reduction of H2O2, which could be explained by the remarkable synergistic effect of the AuNRs and GNs. Therefore, fast amperometric response of this sensor to H2O2 was observed with a linear range of 25-712 mu mol/L and a detection limit of 7.5 mu mol/L. The observed high stability, high sensi-tivity, and high reproducibility of the PVP. GNs. AuNRs films make them promising for the reliable and durable detection of H2O2.
