Abstract
For the first time antimony vanadium oxide-TiO2 (SbV-T) nanocomposite was synthesized via sol-gel method to improve the photocatalytic efficiency of TiO2 . The samples were characterized by FT-IR, XRD, SEM, EDX, and DRS. To investigate the photocatalytic activity of the samples, the photodegradation of methyl orange was carried out under visible light irradiation with pure TiO2 , SbVO4 , and SbVO4 -TiO2 nanocomposite. The SbV-T photocatalyst exhibited higher visible light driven photocatalytic efficiency to degrade MO dye. Furthermore the effect of SbVO4 and cationic vacancies in the photocatalytic activity of the SbV-T sample are described.
