Abstract
Electrochemical sensing is one of the most powerful tools used for the detection of toxic reagents or for examining health issues. In the present work, we have studied the effect of reduced graphene oxide (RGO) in MoS2-RGO nanocomposite for sensing of ascorbic acid. For synthesizing MoS2-RGO nanocomposite, an in-situ microwave-assisted technique has been used and further confirmation of the formation of nanocomposites is done by using field emission scanning electron microscopy, X-ray diffraction, and Raman Spectroscopy. Electrochemical measurements are taken by cyclic voltammetry, differential pulse voltammetry (DPV), and impedance spectroscopy (EIS). Designed sensing material has displayed a noticeable linear increase of current with the concentration of the analyte. It has shown a very precise limit of detection of ~ 0.43 µM/0.16 μM and a remarkable sensitivity of ~ 2.9 µAµM−1 cm−2/1508 Ω μM−1 cm−2 with DPV/EIS. An inductive behavior observed in the Nyquist plots, due to the intercalation process on the surface of the electrode and dissociation of analyte in the buffer solution, was found responsible for the remarkable sensing demeanor of MoS2-RGO@GCE towards ascorbic-acid.
