The Visible Light Activity of the TiO2 and TiO2:V4+ Photocatalyst
TiO2 and vanadium‐doped TiO2 nanoparticles were synthesized by using the hydrothermal method. The V doping contents are 0.0; 0.1; 0.3; 0.5; 0.7 and 0.9% molar. The vanadium‐doped TiO2 nanoparticles have identical anatase phase with an average crystal size of 10‐20nm. The oleic acid and ethanol solve...

| description | TiO2 and vanadium‐doped TiO2 nanoparticles
were synthesized by using the hydrothermal method. The
V doping contents are 0.0; 0.1; 0.3; 0.5; 0.7 and 0.9% molar.
The vanadium‐doped TiO2 nanoparticles have identical
anatase phase with an average crystal size of 10‐20nm. The
oleic acid and ethanol solvents with different molar
concentrations can make spherical nanograins, or stick form
grains, which influence the photo activity of the materials.
The absorption spectra of doped samples exhibited longtailed
absorption in the visible light region above 380nm.
The visible light photocatalytic activity was evaluated by
the degradation of phenol aqueous solutions; after 360
min. under the visible irradiation, the normalized
concentration of phenol decreased to 9%. |
