초록
Titanium dioxide (TiO2), which is one of the most basic materials in our daily life, plays a key role for environment purification. We synthesized TiO2 nanoparticles by the hydrolysis reactions of titanium tetraisopropoxide using HNO3 as a peptizing agent or CH3COOH as a chelating agent in the sol-gel method. The powder consisted of a rod shape or a spherical shape according to the concentration and kind of acid. The physical properties of TiO2 nanoparticles were investigated with X-ray diffraction, SEM, BET analysis, and UV-Vis spectrophotometer.
