One Step Synthesis of Carbon Nitride/Carbon Nanotube Composite Nanomaterials Modified Electrode for Sensitive Electrochemical Detection of Bisphenol A

Abstract

In this work, RCN/WCNTs nanocomposites were synthesized using a one-step method and characterized using SEM, XPS, FTIR. An electrochemical sensor capable of sensitive and rapid detection of BPA was developed by modifying RCN/WCNTs nanocomposites on a glassy carbon electrode. The sensor exhibited excellent electrochemical response to BPA in 0.2 M PBS (pH 7.0) under optimal selection conditions. The linear range of the sensor was 0.01–43 μM, and the detection limit (S/N = 3) was 0.0017 μM. In addition, the sensor exhibited good immunity, stability and reproducibility. And it was applied to the detection of real samples.
