Abstract
Ag–Fe2O3–RGO nanocomposites were successfully synthesized via hydrothermal and chemical reduction method. Based on this nanocomposite, a novel non-enzymatic hydrogen peroxide sensor was fabricated. Field emission scanning electron microscopy, X-ray diffraction spectroscopy, Transmission electron microscopic, Energy-dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy were used for characterization of the nanocomposites, which proved that Ag NPs were well dispersed on Fe2O3–RGO. Electrochemical investigations indicated that the obtained Ag–Fe2O3–RGO nanocomposites had excellent electrocatalytic performance toward H2O2 reduction. The linear range for H2O2 was estimated to be from 1.6 × 10−6 to 5.7 × 10−2 mol L−1 with a sensitivity of 50.8 μA mM−1 cm−2 and a detection limit of 0.5 μmol L−1 (S/N = 3).
