Abstract：
Titania of different crystalline structures and morphology was prepared by the low temperature dissolution-reprecipitation process (LTDRP) of amorphous precursors in various acidic mediums at 70 degrees C for 8 h. The effects of different acids on the crystalline and morphology of titania nanostructures were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Results showed that HCl, HNO3 and their mixture favored the formation of rod-like rutile TiO2, while H2SO4 and its mixture with HCl or HNO3 retarded the formation of rutile but favored the formation of the anatase phase of with an irregular shape. The mechanism of the formation of various titania nanostructures was also discussed. (C) 2008 Published by Elsevier B.V.
