Rapid synthesis of Cu2O/CuO/rGO with enhanced sensitivity for ascorbic acid biosensing
In this study, Cu2O/CuO/reduced graphene oxide (rGO) was synthesized through a rapid and convenient microwave-assisted hydrothermal method. The crystal structure and morphology of the as-prepared product were characterized using X-ray diffraction (XRD), field-emission-scanning electron microscopy (F...

| description | In this study, Cu2O/CuO/reduced graphene oxide (rGO) was synthesized through a rapid and convenient microwave-assisted hydrothermal method. The crystal structure and morphology of the as-prepared product were characterized using X-ray diffraction (XRD), field-emission-scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The electrochemical performance of the novel Cu2O/CuO/rGO biosensor was investigated via cyclic voltammetry. The biosensor was evaluated for ascorbic acid (AA) detection and exhibited a wide linear range of 100 μM–1000 μM, a low detection limit of 0.301 μM, and a sensitivity of 1375.486 μA mM−1 cm−2.
•Cu2O/CuO/reduced graphene oxide was synthesized through a rapid and convenient microwave-assisted hydrothermal method.•The Cu2O/CuO/reduced graphene oxide was applied to ascorbic acid biosensor.•The detection limit is 0.301 μM over wide linear detection ranges up to 1000 μM.•The sensitivity is 1375.486 μA mM−1 cm−2. |
