Photocatalytic Activity of W Doped Ta₂O₅ Particles for Methylene Blue Degradation under UV-Light

Abstract:

Tungsten doped tantalum oxide (W-Ta₂O₅) particles were synthesized by a low temperature hydrothermal method. The phase structure of W-Ta₂O₅ particles was characterized by X-ray diffraction (XRD). The XRD results indicated that the samples belonged to orthorhombic crystal. The photocatalytic activity of samples was investigated with degradation methylene blue (MB) under ultraviolet light. The degradation efficiency of MB under the catalysis of W-Ta₂O₅ particles attained 91% when the reaction time was 7 h. The kinetics of MB degradation was respect to the first-order in the presence of the photocatalysts.
