Novel Nanozyme Swiftly Breaks Down Antibiotics in Water

Scientists have successfully tested a novel nanozyme—a synthetic material designed to mimic the catalytic behaviour of natural enzymes—that can degrade six widely used antibiotics. The material, identified as Co0.5Fe0.5Fe2O4, achieved near-complete removal of drugs including ciprofloxacin, azithromycin, and amoxicillin under optimal conditions.

The study highlights the efficiency of this new catalyst. Operating at a neutral pH of 7 and room temperature, the reaction requires only 15 minutes to process the contaminants in the presence of hydrogen peroxide. Unlike conventional catalysts that often require external activation, this nanozyme demonstrates superior activity and stability on its own. Kinetic studies confirmed its high reaction velocity, making it a potent tool for environmental remediation.

Crucially, the research went beyond simple removal. Using mass spectrometry and total organic carbon analysis, the team tracked the degradation pathways to ensure the antibiotics were fully mineralised. This confirms that the pollutants are converted into harmless carbon dioxide and water, rather than leaving behind toxic intermediate compounds. These findings point toward a more energy-efficient, sustainable strategy for treating pharmaceutical wastewater.
