Effect of Sonication Time and Calcination Temperature on Physical Properties of Titanium Dioxide Synthesized via Sonochemical-Assisted Process

Abstract:

Titanium dioxide nanoparticles (TiO₂) were successfully synthesized via a sonochemical-assisted process using titanium isopropoxide as the titanium sources and calcination process at 300-500 °C. The effect of sonication time and heat treatment temperature on structural and nanostructure properties of the nanoparticles were characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM) and transmission electron microscope (TEM). The XRD and Raman results indicated that the crystalline of as-sonochemically synthesized TiO₂ nanoparticles corresponded to anatase phase of TiO₂ after sonication for 30 mim. The high quality crystalline anatase phase and increasing of crystalline size can be obtained after calcinations process.
