Titanium Dioxide Nanoparticles : Synthesis, X-Ray Line Analysis and Chemical Composition Study

Chenari, Hossein Mahmoudi; Seibel, Christoph; Hauschild, Dirk; Reinert, Friedrich; Abdollahian, Hossein

TiO$_{2}$ nanoparticleshave been synthesized by the sol-gel method using titanium alkoxide and isopropanolas a precursor. The structural properties and chemical composition of the TiO$_{2}$ nanoparticles were studied usingX-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy.The X-ray powder diffraction pattern confirms that the particles are mainly composed of the anatase phase with the preferential orientation along [101] direction.The physical parameters such as strain, stress and energy density were investigated from the Williamson- Hall (W-H) plot assuming a uniform deformation model (UDM), and uniform deformation energy density model (UDEDM). The W-H analysis shows an anisotropic nature of the strain in nanopowders. The scanning electron microscopy image shows clear TiO$_{2}$ nanoparticles with particle sizes varying from 60 to 80nm. The results of mean particle size of TiO$_{2}$ nanoparticles show an inter correlation with the W-H analysis and SEM results. Our X-ray photoelectron spectroscopy spectra show that nearly a complete amount of titanium has reacted to TiO$_{2}$.
