| Abstract |
Photocatalyst is considered to be a qualified candidate and has been attracting much attention for the degradation of toxic organic pollutants environment-friendly under light expose. The tungstate based materials such as Y2WO6, CaWO4, ZnWO4 and Bi2WO6, have been investigated widely for their electric, optical and environmental applications. 2,4,5-Trichlorophenoxy acetic acid (2,4,5-T) is one of the most widely used herbicides which cause irretrievable damage to the environment. We prepared Eu-doped Bi2WO6 by one-step hydrothermal method. The morphologies were characterized by using XRD, XPS, and SEM. Results show that Eu-doped Bi2WO6/H2O2 system exhibits high photodegradation performance for 2,4,5-T. The effects of dopands, H2O2, and pH on photodegradation were investigated and the stability and available reusability were also evaluated.
Keywords: Photocatalyst, 2,4,5-Trichlorophenoxy acetic acid, degradation
