Physicochemical and magnetic properties of pure and Fe doped TiO2 nanoparticles synthesized by sol-gel method

Pure and iron-doped TiO2 nanoparticles (NPs) for different moles were synthesized by the sol-gel method. The synthesized products were characterized by sophisticated instrumental techniques such as powder X-ray diffraction (XRD), Scanning Electron Microscope (SEM), ultraviolet-visible spectroscopy (UV-Vis) and vibrational sample magnetometer (VSM). XRD pattern confirmed the Rutile structure of Pure TiO2 and Fe doped TiO2 NPs. The doping of Fe into TiO2 proved a great decrease in the size of nanoparticles as compared to undoped TiO2. The various functional groups were identified using FTIR analysis. The surface morphology of pure and Fe doped TiO2 nanoparticles were revealed by scanning electron microscopic analysis. The SEM micrographs revealed flakes like structure of pure and Fe doped TiO2 NPs. UV-Vis Spectrometer showed a sharp absorption edge for pure TiO2 in the ultraviolet region at a wavelength of about 375 nm and the absorption edge for Fe doped TiO2 NPs at a wavelength of about 339 nm. Vibrating Sample Magnetometer (VSM) revealed the ferromagnetic property. The value of magnetic moment showed an increase due to the suitable moles of Fe in TiO2 NPs. (c) 2020 Elsevier Ltd.
