Investigation of Morphological, Elemental, Structural, and Optical Properties of Fe-Doped TiO2 Nanoparticles

Abstract

In this research, Fe-doped TiO2 nanoparticles were synthesized by sol-gel technique followed by annealing at 450 oC in a vacuum. The effects of Fe-doping on the morphological, elemental, structural and optical properties of TiO2 nanoparticles have been investigated. XRD analysis was performed to examine the structural properties of synthesized pure TiO2 nanoparticles and Fe-doped TiO2 nanoparticles. Surface analysis was done using Scanning Electron Microscopy. Optical properties were determined using UV/Vis spectroscopy. Morphological analysis revealed that TiO2 nanoparticles have a spherical shape. EDX analysis confirmed the elemental composition of Fe-doped TiO2 nanoparticles. XRD patterns showed that diffraction peaks can be attributed to TiO2 with the anatase phase.
