Abstract
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.
