Abstract
In this work, we have developed Silver nanowires constructed by the sustainable polyol method. The as-synthesized nanowires are isolated and characterized with various spectroscopic methods like UV-Visible spectrophotometer, X-ray diffraction, and surface morphology analysis through Scanning Electron Microscopy (SEM). The entire analysis has well explained the formation of nanowires proceeded to be an electrocatalytic sensor. To investigate the electrocatalytic activity of as-synthesized silver nanowires, cyclic voltammetry (CV) and Differential Pulse Voltammetry (DPV) systems were utilized. The silver nanowire fabricated over GCE and applied as an electrocatalyst sensor towards the determination of carcinogenic Hydrazine. To investigate the lower concentration ranges and detection limit differential pulse voltammetry method were used. The fabricated sensor gives a very good linear range and the limit of detection for determination of hydrazine was attained to be 0.01 - 260 μM and 0.06 μM correspondingly. The as-prepared AgNWs/GCE exposed superior selectivity, storage stability, and reproducibility for the determination of Hz. On affording the above-stated conclusions, we expectantly tested our proposed sensor for real-time monitoring.
