One-Step Synthesis of Nanostructure Phase Pure TiO₂(B)

Abstract

We report a successful synthesis of nanostructure phase-pure TiO₂(B) by one-step hydrothermal process. The process was performed in a 10 mL ethanol and 30 mL glycol solution at 200°C for 24 h using 0.3 mL titanium tetrachloride. The prepared materials were characterized by TEM and XRD, which provide evidence that nanostructure phase-pure TiO₂(B) can be directly produced without ion exchange or further thermal treatment. Furthermore, the morphology and the phase of resultant materials can be controlled easily through changing reaction conditions.
