Synthesis of TiOF₂ Ball-Flowers and the Phase Transitions to TiO₂

Abstract:

In the present work, TiOF₂ ball-flowers were successfully synthesized through a simple low temperature hydrothermal route using titanium butoxide and hydrofluoric acid as precursors. The effect of synthesis temperature on the morphology of TiOF₂ ball-flowers was also studied by scanning electron microscopy (SEM). The crystal characteristics of TiOF₂ were analyzed based on X-ray powder diffraction (XRD) and transmission electron microscopy (TEM), which revealed that the TiOF₂ ball-flowers were consist of hexagonal and cubic single crystal TiOF₂ sheets. After an annealing treatment of 500°C for 2h, the single crystal TiOF₂ sheets were converted to single crystal anatase TiO2 sheets exposed with {116} and {001} facets exposed respectively.
