PG - 130874 LID - S0045-6535(21)01345-X [pii] LID - 10.1016/j.chemosphere.2021.130874 [doi] AB - Transition metal chalcogenides (TMCs) have great potential in diverse electrochemical technologies owing to their unique characteristics. In the present work, we portray the design and synthesis of Vanadium selenide (V(2)Se(9))/reduced graphene oxide (rGO) forming a two-dimensional (2D) hybrid nanocomposite via a simple hydrothermal method. The successfully synthesized nanocomposite underwent in-depth surface and morphological characterizations by XRD, Raman spectroscopy, XPS, TEM, STEM and its potential as an electro catalyst was investigated by using glassy carbon electrode (GCE) for the detection of 2,4,6-trichlorophenol (TCP). The structural features favored a high charge transfer ratio, high surface area as well as excellent conductivity and catalytic activity. The V(2)Se(9)/rGO/GCE modified electrode showed a low charge transfer resistance (R(ct)) of 54.057 Omega cm(2), a decent detection limit (LOD) of 35.07 nM and a very high sensitivity of 22 muA muM(-1) cm(-2) in a working range of 0.001 muM-1150 muM. This is due to the active proton interaction, surface enhancement, and positive synergistic effect between rGO and V(2)Se(9). The proposed sensor has good detection potential in agricultural soil, river water, fish, and beverage samples like wine and apple juice. The obtained results from our investigation would elucidate the application of the catalyst in electrochemical sensors. CI - Copyright (c) 2021 Elsevier Ltd. All rights reserved.
