Spectroscopic analysis of plant trace element incorporated silver nanoparticles synthesis from Datura metel l.

Abstract

Here in we report, silver nanoparticles (Ag NPs) prepared from leaf extract of Datura metel L. via green synthesis method. Datura metel L. is an herbal medicinal plant of solanaceae family. The as - prepared Ag NPs characterized employing UV-Vis spectrometer, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDAX) techniques. The appearance of Surface Plasmon Resonance (SPR) peak at 415 nm suggested that creation of Ag NPs in UV-Vis spectrum. XRD pattern showed face centered cubic crystal structure of Ag NPs with organometallic complex phase. Peaks in FTIR spectrum reveal the existence of biomolecules. SEM image illustrate their clastic rock morphology and EDAX profile authenticate the company of Ag and plant trace element. The Cyclic voltammetry (CV), Choronopotentiometry, and Electrochemical impedance spectroscopy (EIS) analysis were performed as prepared Ag electrode. The specific capacitance of 267.59 F/g at 0.5 A/g and cyclic retention of 83.7% after charge-discharge 5000 cycles are obtained. Hence this material could be utilized as Supercapacitor energy storage devices.
