Abstract
The synthesis of new metal alkoxides possessing unique structures and properties is of great significance for the investigation of sol-gel processes as well as the evolution of metal alkoxide chemistry. In this work, glycolato titanium was synthesized directly from inexpensive starting material titanium dioxide (titania), TiO2, ethylene glycol and TETA as a base catalyst via the Oxide One Pot Synthesis (OOPS) process. The product was characterized using TGA, C13 -NMR, EA, MS and FTIR. Phase transition and morphology of the product were investigated using XRD and SEM, respectively Glycolato titanium was used as a precursor to produce anatase titania by sol-gel technique. The processing conditions affected the gelation time. The higher acid and water ratios resulted in longer gelation time, measured by cone-and-plate rheometer. Moreover, the surface area of as-prepared titania was affected by gelation times and the calcination temperatures. The calcined products, anatase titania, had a high surface area of 120 m2/g.
