Abstract

Photocatalytic water treatment over bare WO3 under visible light irradiation combined with ozonation (O3/vis/WO3) was investigated using an aqueous phenol solution as model wastewater. The O 3/vis/WO3 treatment exhibited a much higher total organic carbon removal than ozonation alone. Bare WO3 was found to function as an active visible-light-responsive photocatalyst for decomposition of organic compounds in the presence of ozone, which readily reacts with photoexcited electrons in the conduction band of WO3.
