摘要：
Developing efficient and sensitive electrochemical sensors is crucial to environmental pollutant detection. In this study, we prepared a copper sulfide-loaded boron-nitrogen co-doped carbon (CuS-BCN) composite using a hydrothermal method. The physicochemical properties were characterized by various techniques, which confirmed the successful preparation of CuS-BCN composites. After optimization, a CuS-BCN modified glassy carbon electrode (CuS-BCN/GCE) was developed as a senor and used for electrochemical detection of nitrobenzene (NB) via square wave voltammetry. Two detection ranges were obtained:0.5-150 & mu;M and 150-1000 & mu;M, with low detection limits of 0.12 & mu;M. In addition, the sensor exhibited excellent repeatability, reproducibility, stability, and immunity against interference. CuS-BCN/GCE exhibited high sensitivity for detecting NB in actual water samples. Hence, in this study, a new and promising electrochemical sensor for the detection of NB was successfully fabricated.
