Rapid and efficient determination of Bisphenol A using reduced graphene oxide wrapped barium/molybdenum oxide nanocomposite

Because of its toxicity and ubiquity in the environment, Bisphenol A (BA) is a prominent endocrine-disrupting compound widely employed in polycarbonate plastics and epoxy resins. BA causes severe health risks for humans. To resolve this, we crafted a selective electrochemical sensor through an efficient electrocatalyst, reduced graphene oxide (RGO) wrapped barium oxide/molybdenum oxide (BMO) nanorod, developed via the hydrothermal method. BMO/RGO nanocomposite was characterized and employed for electrocatalytic performance. BMO displays admirable selectivity, stability, and sensitivity for the determination of BA. Differential pulse voltammetry (DPV) was used for the electrocatalytic study of BMO/RGO nanocomposite for detecting BA. Our proposed sensor displayed a linear enhancement of current when the concentration of BA was increased from 0.01 to 723 μM with a limit of detection (LOD) of 0.004 μM. Furthermore, the proposed sensor is a tool for the rapid and sensitive detection of environmental samples.
