Efficient degradation of organic compounds in water is also challenge for wastewater treatment. Photocatalytic degradation based on multifunctional semiconductor materials has attracted great attention as a prospective method and is highly desirable. Here, we investigated the photocatalytic performance of Pt-supported TiO2 photocatalyst in different crystal structures (rutile, rutile/anatase, anatase) for degradation of methylene blue dye. The morphology and structural properties of TiO2 nanoparticles were tested using field emission scanning electron microscope (FESEM) and X-ray diffraction analysis (XRD) techniques. Moreover, the photocatalytic activities over noble metal supported anatase/rutile titania catalysts (Pd/TiO2, Pt/TiO2, and Ru/TiO2) were evaluated by degrading the methylene blue dye under solar light irradiation, and Pt/TiO2 contributed the highest decomposition efficiency within 20 min irradiation. A possible reaction mechanism for the catalytic oxidation of methylene blue was proposed. |
