Abstract:

In this study, we first report the selective synthesis of TiO2 nanorods of pure rutile, anatase and brookite TiO2 by the hydrothermal treatment of precursor titanate nanosheets. The synthesized TiO2 nanorods exhibit highly crystalline structure with different phases and morphologies. The experimental results indicate that morphologies of products depended significantly on the pH values of the reaction process. Following this, a possible model, dissolving-recrystallizing-growing, was proposed for the formation of TiO2 nanorods with different phases.
