Non-enzymatic approach of H2O2 and glucose sensing using NiO–MoS2-derived electrochemical sensor
At present, selective and accurate determination of hydrogen peroxide (H2O2) and glucose has become essential for routine diagnosis. The present work demonstrates the hydrothermal synthesis of NiO nanosheet (NS)–MoS2-based composite system for non-enzymatic electrochemical detection of H2O2 and glucose. To understand the structure, morphology and elemental constituents of the prepared composite system, various characterization techniques were employed, namely XRD, FTIR, FESEM, TEM and EDX. Redox activity and charge transfer process of the NiO–MoS2-based sensor electrode towards H2O2 and glucose were realized via using electrochemical techniques: cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry. To be mentioned, limit of detection (LOD) and sensitivity for detection of H2O2 are calculated to be 3 µM and 3925 µA mM−1 cm−2, respectively, under the linear range of 5–455 µM in 0.1 M PBS solution. Similarly, the LOD and sensitivity for sensing glucose is estimated to be 3.53 µM and 1880 µA mM−1 cm−2, respectively, under the linear range of 5–370 µM in 0.1 M NaOH solution. The cost-effective fabricated sensor exhibited good stability with a high selectivity towards the specific analytes only.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
