Photocatalytic Degradation of PCB 153 Using Fe <sub>3</sub> O <sub>4</sub> @SiO <sub>2</sub> @TiO <sub>2</sub> ‐Co Core‐Shell Nanocomposite
Abstract This study investigates the photocatalytic degradation of PCB 153 using Fe 3 O 4 @SiO 2 @TiO 2 ‐Co core‐shell nanocomposites under LED irradiation. The unique core‐shell structure, incorporating a magnetic Fe 3 O 4 core, a protective SiO2 layer, and a photoactive TiO 2 shell doped with Co, enhances light absorption, charge separation, and stability. The effects of various parameters, including catalyst dosage, initial pollutant concentration, solution pH, H 2 O 2 concentration, reaction time, and cosolvent type, were investigated to optimize the degradation process. The results demonstrated the high efficiency of the Fe 3 O 4 @SiO 2 @TiO 2 ‐Co nanocomposite in degrading PCB 153, with a maximum degradation efficiency of 95.2% under optimal conditions. The magnetic properties of the Fe 3 O 4 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.
