Synthesis of Uranium Doped TiO2 Nanomaterial and its Visible Light Degradation Property

Abstract:

Article Preview

Uranium doped TiO2 (U-TiO2) nanomaterials, determined by scanning electron micro- graphy (SEM), were successfully synthesized via a simple, effective and environmental benign solid state reaction route. The characterizations via XRD and XPS showed that the uranium has been entered into the framework of anatase TiO2. The DRUV-Vis revealed that the adsorption region of U-TiO2 nanomaterials shifts to the visible light region compared with the pure TiO2. Moreover, the U-TiO2 nanomaterials for photodegradation of quinoline showed a good photocatalytic properties under visible light irradiation. At 298K, within 60 min visible light irradiation, 54.9 % of the initial quinoline was degraded by the U-TiO2 (U/Ti=3:20) catalyst. The visible light degradation rate of the U-TiO2 nanomaterials is negative to the pH value of surface but positive to the visible light absorption range.
