Abstract

In the present study, TiO2 and Nd doped TiO2 nanoparticle was synthesized through Sol-gel method with different molar ratio and different starting material. The synthesized nanoparticle was characterized by XRD, UVVis, PL, FE-SEM, HR-TEM, and EDS analysis. The X-ray diffraction pattern confirms tetragonal anatase phase
with average crystallite size of 14–10 nm. The influence of phase transition was identified by the addition of
dopant Nd. The calculated band gap is in the range of 3.48–3.44 eV. Near UV and blue emission in PL spectrum
indicate the presence of crystal defects in TiO2 lattice. The structural morphology of the prepared sample was
analyzed by FESEM. The average particle size of the sample was determined by TEM analysis. The elemental
compositions and incorporation of Nd ions into the TiO2 nanoparticles was detected by using energy dispersive
spectra analysis. The antibacterial activity of pure TiO2 and Nd doped TiO2 nanoparticle was tested for different
bacterial organisms like Escherichia coli (Gram-negative) and staphylococcus aureas (Gram-positive) bacteria.
The photo catalytic activity of the prepared samples on degradation of Methylene Blue and Congo Red under
ultraviolet irradiation were also studied.
