Abstract

This study investigates the photocatalytic degradation of PCB 153 using Fe₃O₄@SiO₂@TiO₂-Co core-shell nanocomposites under LED irradiation. The unique core-shell structure, incorporating a magnetic Fe₃O₄ core, a protective SiO2 layer, and a photoactive TiO₂ shell doped with Co, enhances light absorption, charge separation, and stability. The effects of various parameters, including catalyst dosage, initial pollutant concentration, solution pH, H₂O₂ concentration, reaction time, and cosolvent type, were investigated to optimize the degradation process. The results demonstrated the high efficiency of the Fe₃O₄@SiO₂@TiO₂-Co nanocomposite in degrading PCB 153, with a maximum degradation efficiency of 95.2% under optimal conditions. The magnetic properties of the Fe₃O₄ core enable easy separation and recovery of the catalyst, making it a sustainable and cost-effective solution. This study provides valuable insights into the design and application of advanced photocatalysts for environmental remediation.
