Synergistic effects of N/S co-doped carbon and oxygen vacancies on peony-like BiOBr toward enhanced photocatalytic degradation of pollutants.

N/S co-doped carbon and oxygen vacancies in peony-like BiOBr enhance photocatalytic degradation of pollutants by over 90% under visible light.

• Why it matters: Efficient removal of emerging aquatic contaminants remains challenging due to secondary pollution and catalyst recovery issues, necessitating improved photocatalytic materials.
• What they did: Researchers synthesized an N/S co-doped carbon-coated BiOBr with oxygen vacancies using hydrothermal methods and integrated it into a PVDF membrane, achieving superior photocatalytic performance.
• The result: The optimized composite achieved over 92% degradation of ciprofloxacin in 60 minutes, demonstrating the potential of heterojunction engineering for advanced environmental remediation technologies.
