Abstract:
TiO 2 and Vanadium doped TiO 2 nanoparticles were synthesized by hydrothermal method. The solvents are water, oleic acid, or oxalic acid, which have affected the forms and sizes of the grains in the samples. The solvent can make the spherical nanograins, or the stick form grains, what influences the photo activity of the materials. The Vanadium doped TiO 2 nanoparticles had identical anatase phase with average crystal size of 8-20nm. The absorption spectra of doped samples exhibited the long tailed absorption in the visible light region above 380nm. The photocatalytic activity under the irradiation of visible light was evaluated by the degradation of phenol aqueous solutions, which is one of the products from photocatalytic oxidations of benzene. The samples TiO 2 :0.5%V 4+ have visible light photocatalystic activity; after 360min under the visible irradiation the normalized concentration of phenol decreased to 9%.
