Tuning the sunlight-driven photocatalysis via halide variation in BiOX/Bi2WO6/Bi2O3 (X = Cl, Br, I) for ciprofloxacin removal

Key Points

• Ciprofloxacin removal increased significantly with specific halide variations in BiOX composites.
• Performance metrics indicate up to 90% degradation of ciprofloxacin within 120 minutes under sunlight.
• Photocatalytic experiments utilized Bi2WO6 and Bi2O3 mixed with halides for enhanced efficacy.
• The findings suggest optimizing halide compositions could advance wastewater treatment strategies.
