英文摘要 | Metal oxide sols can be prepared from metal alkoxides by hydrolyzation, which has been widely used in synthesis of nano-porous ceramic membranes by sol-gel method. However, the knowledge on hydrolysis mechanism of metal alkoxides is very limited. In this paper, TiO2sols were prepared by controlled hydrolyzation of titanium isopropoxide [Ti(i-OC3H7)4] in isopropanol (i-C3H7OH). The formation of TiO2sols from the initial reactant mixtures with different molar ratios of H2O/Ti(i-OC3H7)4[Ti(i-OC3H7)4:H2O:i-C3H7OH = 1:m:30] was charterized by small angle X-ray scattering (SAXS). The mechanism of formation and growth of colloidal particles is discussed. TiO2sol with a particle size less than 10 nm can be obtained. The formation and growth of colloidal particles are remarkably influenced by the molar ratio of H2O/Ti(i-OC3H7)4. When the molar ratio of H2O/Ti(i-OC3H7)4≥ 2.0, the stability of TiO2sol decreases with the molar ratio of H2O/Ti(i-OC3H7)4increasing. © All Right Reserved. |
