Photocatalytic Degradation Research of p-Xylene Using Doped TiO₂ Under Different Conditions

Abstract

As the development of the \golden waterway" for the Yangtze River and the formation of the Three Gorges Reservoir area, the inland river shipping of chemical is increasing in China. At the same time, the risk of chemical leak accident is on the rising. Recent years, photo-catalyst has attracted great interest in environmental pollution treating for its unique properties. In order to improve its ability in pollution degradation, di®erent kinds of doped TiO 2 are made in this work. Since the toxicity and transportation quantity, p-Xylene is researched as the aim chemical in this research. The in°uence of di®erent catalyst, lighting time and reaction temperature to p-Xylene degradation rate are studied respectively in detail.
