Magnetically Nanomaterial as Photocatalyst for Degraded Tetracycline under UV Light Active

Abstract

The development of efficient photocatalysts for the degradation of emerging pollutants are still a challenging task. Hence, a novel γ-FeOOH-Fe₃O₄@SiO₂@TiO₂-Fe₂O₃ (γ-FST) magnetic core-shell nanomaterial photocatalyst was successfully synthesized using a sol-gel method combined with anaerobic calcination It compared with Fe₃O₄@SiO₂@TiO₂-Fe₂O₃ (FST) and used for photodegradation of tetracycline(TC). The structural, optical, magnetic, and morphological properties of the nanocomposites were investigated using a series of complementary analytical techniques.The γ-FST nanocomposites demonstrated excellent reproducibility and maintaining high stability after three cycles. Active species trapping experiments indicated that holes (h⁺) and hydroxyl radicals (•OH) played a pivotal role in the degradation of TC. Furthermore, γ-FST exhibited saturation magnetization values 12.47 times higher than FST.
