Silver bismuth sulphide (AgBiS2)-MXene composite as high-performance electrochemical sensing platform for sensitive detection of pollutant 4-nitrophenol
4-Nitrophenol (4-NP) is one of the most common and extensive toxic threats to the environment; hence there is always a need to develop a robust analytical method. In this study, we present MXene-based AgBiS2 nanocomposite as an electrochemical sensing platform for detecting 4-NP. The synergistic combination of MXene and AgBiS2 within the composite structure enhances electrocatalytic performance, resulting in a highly sensitive and selective sensor. The electrochemical performance of the MXene-AgBiS2 modified GCE was evaluated through cyclic voltammetry (CV) and differential pulse voltammetry (DPV) analyses. The sensor exhibited excellent electrochemical properties, including a low detection limit (LOD) of 0.00254 µM (should consider the method how to get such low LOD – due to 10 times of the lowest conc tested S/N = 3, high sensitivity of 5.862 µA µM−1 cm−2, and a wide linear range (0.02–1869 µM). The sensor also demonstrated good selectivity against various interference compounds such as Di-Nitrophenol, Ortho-Nitrophenol, Copper, Cobalt, sodium, Manganese, Zinc, Glucose (GLU), Urea (Ur), Dopamine (DA), Ascorbic acid, and Uric Acid. Along with reproducibility, repeatability, and stability also performed shows, 2.21 %, and 2.71 % respectively. Our nanocomposite sensor, utilizing MXene-based AgBiS2, proves its practicality in real-time tap water analysis. This bridge between lab studies and environmental monitoring marks a significant advancement. The unique properties of our sensor enhance electrochemical sensing, providing a promising solution for swift on-site detection of 4-NP in water, potentially revolutionizing pollutant management.
