TiO2 particles were synthesized through hydrolysis, aging, peptization, heat treatment from titanium tetraisopropoxide(TTIP). As results of study, the characteristics of TiO2 particles such as crystallinity, sol particle size, microstructure and surface characterization, could effectively be controlled by the aging in the synthetic stages of TiO2 sol. The TiO2 sol characteristics controlled by the aging had similar influence to even the post-calcination. In our study, the characteristics of TiO2 particles were analyzed by XRD, FT-IR, Turbidity, HR-TEM, XPS, and BET. Therefore, the characteristics of TiO2 sol and calcined particles were effectively able to control by the aging in the TiO2 sol preparation. |
