Preparation of Nanocrystal TiO2 with Rutile Structure at Lower Temperature from TiOCl2 Solution
TiOCl2 溶液低温水解合成金红石型氧化钛纳米粉

Nanometer titania needle-shaped agglomeration was directly prepared by aging TiOCl2 aqueous solution from room temperature to 60°C. The effect of reaction temperature and stirring on TiO2 crystalline size and morphology were discussed. The results show the morphology of product is pseudo-sphere in the stirring condition. The aging temperatures have no effect on the morphology of product. The TiO2 particles were characterized by TEM and XRD. The result shows the product is nanometer titania needle-shaped agglomeration with rutile structure.
