Abstract
V2O5/TiO2 systems have been obtained by reacting TiO2 (P-25 from Degussa, ca 55% anatase, or a rutilised modification, ca 3% anatase) with gaseous VOCl3. The samples have been characterised by X-ray diffraction, UV–Vis spectrophotometry and nitrogen adsorption at 77 K. For the anatase carrier, a monolayer coverage of V2O5 is achieved, but only 0·46 monolayers are formed with the rutilised support. The specific surface areas decrease upon incorporation of V2O5, and that seems to be well dispersed without forming crystallites.
