Green synthesis and characterization of novel iron particles by using different extracts

Abstract

In this study, iron (Fe) particles are attaining importance for their vital properties and multifunctional applications including hazardous waste treatment, catalytic degradation biomedical treatments, microwave adsorption and medical diagnostic. These particles were prepared by using mango leaves, rose leaves, neem leaves, carom seeds and clove buds through eco-friendly green synthesis under constant stirring and atmospheric pressure at 70 °C temperature. The synthesized Fe particles are in zero valent oxidation state. Different plant extracts plays a vital in reduction and stabilization of nanoparticles along with particular amount polyvinylpyrrolidone (PVP), instead of polyvinyl alcohol (PVA) act as stabilizing agent. The prepared nanoparticles were analyzed by using SEM, XRD, EDX, FTIR, and Uv–vis spectroscopy. The experimental results revealed that size of Fe particles increased with increasing concentration of PVP. Higher concentrations of Fe particles in the prepared sample are confirmed by the FTIR spectra peak depth at 3338 cm−1. Remarkable effect of PVP on the surface of Fe particles investigated by using UV–visible spectrometer (UV-VIS) such that the first absorbance peak observed at 320–325 nm and the second peak observed at 470–475 nm. XRD spectra show the pure (FCC) Fe particles, which are crystalline in nature with peaks at 43.37° with planer reflections of 400, where EDX confirmed the purity of Fe particles and elemental percentage.
