A novel magnetic AC/bentonite/Fe ₃ O ₄ /CeO ₂ nanocomposite catalyst for photocatalytic degradation of persistent chlorinated pesticides in water

nanocomposite demonstrates some key advantages including high adsorption affinity, fast reaction kinetics, broad pollutant applicability, magnetic separability, and significantly shorter treatment time compared with many of those previously reported using cerium-based photocatalysts. These results highlight the potential of this sustainable catalyst system for efficient remediation of POP-contaminated water.
