Year: 2024
Type: conference-paper
Abstract: In this study, the iron oxide/titanium dioxide (α-Fe2O3/TiO2) nanocomposites derived from Logas natural sand were prepared by ball milling method. The effects of milling time on the magnetic, optical properties and chemical composition of the nanocomposites were investigated using vibrating sample magnetometer (VSM), Uv-Vis spectroscopy and X-ray fluorescence (XRF) spectroscopy, respectively. The magnetization measurement results of all the samples showed the presence of ferromagnetic behaviour characterized by their low coercivity value ranged from 360.10 Oe to 86.50Oe. The optical properties of the samples strongly depend on milling time and showed that the band gaps of the iron oxide/titanium dioxide (α-Fe2O3/TiO2) nanocomposites decrease with increasing milling time. Some other elements such as silicon, aluminium and others were detected, which shows that the milled sample is not purely α-Fe2O3/TiO2 nanocomposites as confirmed by X-Ray Fluorescence. This study demonstrates the simple way of preparing the α-Fe2O3/TiO2 nanocomposites for environmental application.
