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 (FESEM), transmission electron microscopy (TEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The electrochemical performance of the...
