摘要：
TiO2 nanoparticles that were synthesized using a chemical vapor condensation (CVC) method were loaded on transition metal oxides (V2O5) using the impregnation method followed by thermal treatment. The primary particle size of the CVC-made TiO2 sample after vanadium was decreased drastically to 5.7 nm. The particle sizes before and after vanadium loading on the commercial TiO2 (Degussa, P25) were similar. The vanadium-loaded CVC-made TiO2 sample exhibited the best absorption performance of visible light from the absorption spectra. Moreover, the CVC method through transition metal impregnation was favorable for its enhanced photocatalytic properties. (C) 2012 Elsevier B.V. All rights reserved.
