An Efficient Voltammetric Sensor Based on Graphene Oxide-Decorated Binary Transition Metal Oxides Bi₂O₃/MnO₂ for Trace Determination of Lead Ions.

ABSTRACT: Herein we present a facile synthesis of the graphene oxide-decorated binary transition metal oxides of Bi₂O₃ and MnO₂ nanocomposites (Bi₂O₃/MnO₂/GO) and their applications in the voltammetric detection of lead ions (Pb²⁺) in water samples. The surface morphologies, crystal structures, electroactive surface area, and charge transferred resistance of the Bi₂O₃/MnO₂/GO nanocomposites were investigated through the scanning electron microscopy (SEM), power X-ray diffraction (XRD), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) techniques, respectively. The Bi₂O₃/MnO₂/GO nanocomposites were further decorated onto the surface of
