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‐Fe 3 O 4 @SiO 2 @TiO 2 ‐Fe 2 O 3 (γ‐FST) magnetic core‐shell nanomaterial photocatalyst was successfully synthesized using a sol‐gel method combined with anaerobic calcination It compared with Fe 3 O 4 @SiO 2 @TiO 2 ‐Fe 2 O 3 (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.
