The presence of pharmaceutical pollutants in water bodies represents a significant environmental and public health concern, largely due to their inherent persistence and potential to induce antibiotic resistance. Advanced oxidation processes (AOPs) that employ peroxymonosulfate (PMS) activation, with high redox potential, have emerged as an effective means of degrading these contaminants. Bismuth oxyiodides (BiOI), which are known for their visible-light photocatalytic properties, demonstrate considerable potential for removal of pharmaceutical pollutants. This study, developed at Thin-film and Nanostructure electrodeposition Group (GE-CPN), examines the synthesis and performance of BiOI-based composites with barium ferrite (BFO) nanoparticles for enhanced PMS activation under visible light. The results obtained regarding degradation and mineralization of tetracycline, demonstrate the material’s robust potential for treating pharmaceutical pollutants in real-world conditions, advancing sustainable water treatment technologies.
