Single Phase Synthesis of Rutile TiO2 Nanoparticles

Abstract

The hydrolysis method was utilized to synthesis TiO nanoparticles as pure rutile phase and ammonia in acidic medium by adjusting the pH around 10. Nano TiO 2 were prepared from TiCl 4 and HPLC grade water as solvent. The synthesized TiO 2 2 nanoparticles was calcined at 400 0 C, 700 0 C and 900 0 C for 4 hours. Structural, morphological and chemical properties of synthesized TiO nanoparticles were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) & Fourier transform infrared microscopy (FTIR) respectively. The experiment indicates that hydrolysis and drying have important effects on the properties of product. On finding shows the formation of pure rutile phase of nano TiO 2 2 in basic medium. The calculated particle size of TiO nanoparticles was in the range of 20-30 nm. Also the structural characterization shows the formation of mixed phase (anatase + rutile) of nano TiO 2 2 particles which indicates the unreacted reaction in acidic medium.
