Abstract
Ultrafine particles (UFP) were prepared by means of the colloidal chemical method. The structure and properties of the as-prepared TiO2 UFP, having be en submitted to different heat-treatment tests, were studied using TEM, XRD , IR, SPS, Raman, XPS and W-vis absorption spectrum. The results of the XPS , SPS and UV-vis absorption spectrum indicated that on the surface of TiO2 UFP, there were surface active species such as Ti3+ and hydroxyl which can improve the photocatalytic activity of TiO2 UFP.
