The Au nanoparticles decorated graphene (AuNPs@Gr)/nickel foam (Gr/NiF) nanocomposite (AuNPs@ Gr/NiF) was prepared by chemical vapor deposition followed by electrophoretic deposition of AuNPs on Gr/NiF. The morphology, microstructure and sensing performance of the as-prepared AuNPs@ Gr/NiF nanocomposite were characterized and measured, respectively by scanning electron microscope, transmission electron microscope, ultraviolet visible spectroscopy and chemical workstation. The asprepared AuNPs@ Gr/NiF nanocomposite was used as the electrode to construct a chemical sensor for the detection of hydrogen peroxide (H2O2). The results showed that the AuNPs distributed homogenously and stably on the surface of Gr/NiF. The chemical sensor exhibits a sensitive and selective performance to the detection of H2O2.
