Effect of Hydrothermal Growth Temperature on the Morphology and Structural Properties of Synthesized TiO_2 Nanowires

摘要

Titanium dioxide nanowires have successfully prepared by hydrothermal method. The effect of hydrothermal growth temperature on the morphology and structural properties of TiO_2 nanowires have been investigated. It was observed that at low temperature of 100°C, the formation of nanowires was at early stage, while hydrothermal treatment at 130°C showed the TiO_2 precursor acquired enough energy for formation of the nanowires. Increased the temperature to 200°C was formed the bundle of nanowires in microsize. The diameter of nanowires increased as the temperature increased. The TiO_2 nanowires produced at temperature of 150°C and annealed at 500°C showed highest crystallinity with anatase phase.
