Titanium carbide MXene and V2O5 composite-based electrochemical sensor for detection of bisphenol A

In recent years, 2D layered titanium carbide (Ti3C2Tx) MXene has been widely used in the electrochemical sensing of various analytes. This paper focuses on fabricating a glassy carbon electrode modified with Ti3C2Tx MXene and V2O5. The electrochemical studies for the detection of bisphenol A (BPA) have been carried out using the modified glassy carbon electrode (GCE) electrode and also the electrochemical oxidation of BPA has been described through cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) techniques. The voltammetric behavior of the material by detecting BPA in different concentrations has been studied. The materials have been synthesized and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Energy-Dispersive X-ray spectroscopy (EDX). The differential pulse voltammetry exhibits a linear range from 414 nM − 31.2 µM with a detection limit of 87 nM for BPA. This novel BPA sensor showed satisfactory results and also it has the potential to create a great platform in the environmental monitoring system.
