Y2O3-WO3 photocatalyst refers to a composite photocatalyst obtained by doping Y2O3 in the matrix WO3, which can be used to treat dye wastewater, such as acid red B - a water-soluble dye mainly used for dyeing wool and silk. Wherein, the doping of Y2O3 improves the photocatalytic activity of WO3.

WO3, as a semiconductor photocatalyst, has been used in research and treatment of printing and dyeing wastewater as early as 1985. At present, it has been gradually applied in the research of the promotion and application of semiconductor photocatalytic technology to treat dye wastewater. Dye wastewater has characteristics of complex specific components, high chroma, large discharge, high toxicity, and poor biodegradability. And it has always been a problem in wastewater treatment. Y2O3-WO3 photocatalyst is the result in the research of using WO3 photocatalysis to treat dye wastewater.
