Synthesis and formation mechanism of Rutile type titanium dioxide using titanium tartarate complex

Abstract

TiO2 is one of the most important industrial material, that has eight polymorphs under room temperature and ordinary pressure. In this study rutile-type TiO2, one of the polymorphs, are prepared by hydrothermal treatment of Ti-tartarate complex in the presence of large amount of H2O2. Prepared rutile was spherical shaped and mono-dispersed with size of about 10 nm. We report possible structure of Ti-tartarate complex with H2O2 and formation mechanism of nano-sized rutile from the complex under hydrothermal reaction.
