“…The intensity of the main anatase peak (101) at 2θ = 25.27 decreased considerably compared to the pure sample. The peaks at 2θ, i.e., 25.24, 39.11, 47.93, and 54.34 degrees related to lattice planes ( 101), ( 200), ( 111), (210), and (002), which are compatible with rutile phase (JCPDS 21-1276) (Abraham & Devi, 2022). From this, we can see clearly that up to the small content of Fe, the TiO2 powders exhibit an anatase phase, and a clear phase transformation from the anatase to rutile occurs as doping of Fe increases.…”

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.
