Photocatalytic oxidation technology has good selectivity, can react at room temperature and pressure under mild conditions, and can degrade organic pollutants into non-toxic and harmless inorganic substances. It is a green technology with important application prospects in the field of energy and environment. In recent years, more and more reports have been reported on photocatalytic oxidation of organic wastewater. Semiconductor materials used are also various, such as titanium dioxide, zinc oxide, Fe₂O₃, CdS, WO₃, etc. The photocatalytic stability of WO₃ is good, but its activity is relatively small.
