Preparation of WO₃ Particles and Their Photocatalytic Properties

Abstract Traditional water treatment avoids waste of resources and secondary pollution, photocatalysis technology has become a research hotspot. This paper uses the hydrothermal method to prepare WO 3 particles. The microstructure and performance of WO 3 were characterized by XRD, SEM, ultraviolet visible light and photocurrent. The results show that the prepared WO 3 is a hexagonal crystal with a particle size of about 200-300 nm, and has good absorption properties in the visible light region. Finally, norfloxacin was used as the target pollutant to evaluate its photocatalytic performance. The results show that the prepared WO 3 can effectively remove antibiotics in sewage.
