Chemical vapour synthesis of V-doped TiO2 nanoparticles and characterization of their photocatalytic activity

TiO2 nanoparticles doped with vanadium (up to 1 at.%) were produced via chemical vapour synthesis (CVS) route. Spherical anatase particles with an average size of 5-15 nm were synthesized. Induced coupled plasma (ICP) and X–ray photoelectron spectroscopy (XPS) analyses indicated that the transition metal was incorporated in the titanium oxide lattice. A shift in absorption edge of the titanium oxide particles with increasing the amount of dopant was noticed. Photodegradation of methylene blue solution revealed the positive influence of vanadium on the photoactivity of anatase TiO2.
