【 摘 要 】

Herein, a novel non-enzymatic glucose sensor was fabricated based on the reduction graphene oxide-persimmon tannin-platinum-palladium alloy (RGO-PT-Pt-Pd) nanocomposite. The RGO-PT-Pt-Pd nanocomposite was prepared through a facile approach with PT as film material and ascorbic acid as reducing agent and characterized by ultraviolet visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), X-Ray diffraction (XRD) and so on. Then, the synthesized RGO-PT-Pt-Pd nanocomposite was employed as an electrode material for non-enzymatic glucose sensing using gold electrode (GE). The RGO-PT-Pt-Pd/GE sensor showed outstanding catalytic activity toward glucose oxidation. The prepared amperometric sensor exhibited a wide linear range of 0.01-0.40 mol/L with a limit of detection (1.43 μmol/L) as well as high stability and fast responsetime (
