Fabrication and Characterization of Sulphur‐doped Graphitic Carbon Nitride Nanosheets as a Highly Selective and Ultrasensitive Electrochemical Sensor for Detection of 2,4‐Dinitrophenol in Real Gym Supplements

Abstract

AbstractHerein, an effective template assisted calcination procedure has been adopted to synthesize the Sulphur‐doped graphitic carbon nitride (SXGCN). Furthermore, the SXGCN/GCE was then utilized for the electrochemical determination of 2,4‐Dinitrophenol (2,4‐DNP). It has been inferred that among the variously prepared SXGCN (x=0 %, 20 %, 40 %, 60 %, 80 %, and 100 %), S80GCN afforded the excellent electrochemical response for detection of 2,4‐DNP. The synthesized SXGCN/GCE (x=80 %) demonstrates with a low detection limit of 0.9083 μM with linear range of 1–90 μM. Furthermore, the practical application of this sensor was successfully proved by detecting spiked 2,4‐dinitrophenol in a real gym supplements sample.
