Abstract
Industrial wastewater, contaminated by dyes and antibiotics, poses significant environmental challenges. We developed Fe-doped Bi 2 WO 6 (Fe:Bi 2 WO 6 ) photocatalysts to enhance the photocatalytic activity and stability of Bi 2 WO 6 . The advanced oxidation processes (AOPs) of Fe, including the photo-Fenton process for rhodamine B (RhB) degradation and peroxymonosulfate (PMS) activation for Cefalexin (CFX) degradation, were investigated. The Fe doping altered the crystallization of Bi 2 WO 6 and improved its photocatalytic performance, achieving 97.7% RhB degradation and 70.6% CFX degradation within 180 min. These results highlighted the potential of Fe:Bi 2 WO 6 photocatalysts in wastewater treatment , emphasizing their stability and high activity across various conditions.
