Abstract
Different Fe2O3/TiO2 nanocomposite ratios have been auto-synthesized from the leaching solution of Egyptian ilmenite ore with and without solvent extraction of soluble iron ions. Hydrolysis-hydrothermal strategy was then implemented for preparation of Fe2O3-TiO2 nanocomposites. The x-ray diffraction results indicated that rutile and hematite were only found at high iron oxide content. Meanwhile, anatase and hematite were the predominant phases at low iron oxide content. High-resolution transmission electron microscopy investigations exhibited nano-rods like morphology and the space lattice distances of TiO2 and Fe2O3 were clearly estimated. Moreover, the chemical composition of different Fe2O3-TiO2 nanocomposites was also elucidated using energy dispersive spectroscopy and Fourier transform infrared analyses techniques. The values of saturation magnetization (Ms) and remanent magnetization (Mr) were noticeably increased by 17.5% and 18.4% with increasing the Fe2O3/TiO2 molar ratio from 1.0 to 3.0, respectively. Field cooling-warming magnetization studies showed that the Morin transition temperature (TM = 200 K) was consistent with the previously published values.
