Abstract: | A novel H3PW12O40/TiO2 (anatase) composite photocatalyst was prepared by a high-intensity ultrasonic method using a lower temperature (80 °C) and was characterized by XRD and FT-IR. Its photocatalytic activity, using solar light, was evaluated through the degradation of organic dye methylene blue (MB) in aqueous. When MB solution (50 mg/l, 200 ml) containing H3PW12O40/TiO2 (anatase) (0.4 g) was degraded by solar irradiation after 90 min, the removal of concentration and TOC of MB reached 95% and 73%, respectively. The photocatalyst activity of H3PW12O40/TiO2 (anatase) was much higher than TiO2 which was prepared in the same way. H3PW12O40/TiO2 remained efficient after five repeated experiments. |
