Green Synthesis of Magnetic Iron Oxide Nanoparticles Using Quince Leaf Extract Coated with SiO2 Using Ultrasonic Treatment

Abstract

Setayesh Souri and Mohammad Kazazi

Today, one of the most effective methods for synthesizing Nanoparticles (Nps) is through plant extracts. The chemical synthesis of Nps is expensive and causes environmental pollution. In this study, quince leaf extract from a tree was used for the green syn- thesis of magnetic iron oxide Nps. The magnetic iron oxide Nps were coated with silicon dioxide Nps and the color change in the solution and the brown precipitates, confirmed the successful green synthesis of magnetic iron oxide Nps. Analyses including Vi- brating Sample Magnetometer (VSM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were performed. The average size of the crystalline magnetite (Fe3O4) Nps was calculated using the Debye-Scherrer formula, which is in the nanometer scale.
