Photocatalytic Degradation of Antibiotics via Exploitation of a Magnetic Nanocomposite: A Green Nanotechnology Approach toward Drug-Contaminated Wastewater Reclamation

“…After magnetically separating it from the solution, drying it, and repeating this process three times, we noticed no significant loss of effectiveness, indicating that the magnetic nanocomposites remain stable and reliable for multiple uses in cleaning up pollutants. 33 , 71 Conclusively, the photocatalyst was successfully recycled by a magnetic separation technique (external magnet) with only a slight decrease (7.4%) in catalytic activity. Green synthesis improved the degradation efficiency, but it did not have any impact on the reusability of the photocatalyst.…”

“…These radicals effectively oxidize and degrade the antibiotic molecules adsorbed onto the surface of the nanocomposite through oxidative and radical-driven reactions, ultimately leading to the transformation of the antibiotics into less harmful byproducts. The magnetic component enables easy separation and recovery of the nanocomposite catalyst from the treated solution using an external magnetic field, enhancing the reusability and practical applicability of the photocatalytic system. − The mechanism of photocatalytic degradation for both antibiotics CIP and AMX is shown in Figure . Fe 3 O 4 creates a reactive species in the presence of UV light, for example, hydroxyl radicals (HO·) as indicated by the accompanying reactions: Fe 3 normalO 4 + h v → Fe 3 normalO 4 ( − eCB ) + Fe 3 normalO 4 ( + hVB ) Fe 3 normalO 4 ( + hVB ) + 2H 2 normalO → 2HO . + 2H + · OH + organic .25em pollutants → degraded .25em products …”

Photocatalytic Degradation of Rhodamine B Dye by Nanocomposites: A Review

“…A variety of possible photo-sensitive nano-semiconductor metal halide/oxides/sulphide, such as TiO2, ZnO, CuO, BiFeO3 and Carbon-based nanostructures have been produced and employed as photocatalysts for water purification, thanks to rapid advances in nanotechnology [11]. This innovative interdisciplinary branch of science and technology leads to the formation of different morphologies like nanoparticles [12-16][17], nanotubes [18,19], nanorods [20,21], nanocubes [22] and nanosheets [23] by using numerous advanced methods such as hydrothermal, solvothermal, sol-gel, microwave, co-precipitation methods [24] with different applications in many fields such as from basic chemistry [25][26][27][28], physics [29][30][31] to the advanced electronics [32][33][34][35][36], nanotechnology [37][38][39][40][41], biotechnology [42][43][44][45][46][47] by altering the properties like mechanical [17,48] physical [49][50][51] and magnetic [52,53] so they come up with an ideal of environmental friendly [54], with a motto of decreasing the pollutions [55,…”
