Electrochemical Synthesis of Tungstate Bimetallic Nanoparticles with Application in Electrocatalytic Determination of Paracetamol

Abstract In this work binary, cobalt‐nickel tungstate nanoparticles (CoNiWO 4 ‐NPs) were electrochemically synthesized on glassy carbon electrode. The electrochemically synthesized nanoparticles have been characterized using different techniques such as X‐ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐ray spectrometer (EDX), and elemental distribution maps. Electrochemical impedance spectroscopy (EIS) has also been used to determine the electrocatalytic properties of CoNiWO 4 nanoparticles. The electrochemical behaviour of paracetamol was studied on a glassy carbon electrode modified with CoNiWO 4 ‐NPs. This sensor exhibits excellent electrocatalytic properties for the oxidation of paracetamol and can be successfully used to determine paracetamol in various samples, including paracetamol tablets and syrup.
