Abstract
Ultrafine particles (UFP) were prepared by means of the colloidal chemical method. The structure and properties of the as-prepared TiO2 UFP, having been submitted to different heat-treatment tests, were studied using TEM, XRD, IR, SPS, Raman, XPS and UV–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.
