摘要	We describe a simple method for preparing Au-TiO2/graphene (GR) nanocomposite by deposition of Au nanoparticles (NPs) on TiO2/GR substrates. The as-prepared Au-TiO2/GR was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The presence of Au NPs on TiO2/GR surface remarkably improves the electrocatalytic activity towards the oxidation of hydrogen peroxide (H2O2) and beta-nicotinamide adenine dinucleotide (NADH). The Au-TiO2/GR modified glassy carbon (GC) electrode exhibits good amperometric response to H2O2 and NADH, with linear range from 10 to 200 mu M and 10 to 240 mu M, and detection limit of 0.7 and 0.2 mu M, respectively.
