Title: | TiO?hydrosols with high activity for photocatalytic degradation of formaldehyde in a gaseous phase | Authors: | Liu, TX Li, FB Li, XZ |
Issue Date: | 21-Mar-2008 | Source: | Journal of hazardous materials, 21 Mar. 2008, v. 152, no. 1, p. 347-355 | Abstract: | Two types of TiO?hydrosols (TOSO and HTO) were prepared from titanium sulfate (TiOSO?)and metatitanic acid (H?TiO?) by a chemical precipitation¡Vpeptization method, respectively. The prepared hydrosols were characterized by means of X-ray diffraction, particle size distribution, scanning electron microscopy, UV¡Vvis spectroscopy, Fourier transform infrared spectroscopy, Brunauer¡VEmmett¡VTeller and Barret¡VJoyner¡VHalender methods. The results showed that the TiO?hydrosols with an anatase crystal structure had smaller particle sizes, higher surface areas, larger pore volume, and higher transparence than Degussa P-25 suspension.
