The investigation of the efficiency recycling, rapid separation, high catalytic performance photocatalyst materials, and properties material after photocatalytic process (after use) are considered important for photodegradation applications. Green-synthesized hybrid magnetic/semiconductor nanocomposites utilizing Moringa oleifera leaf extract exhibit excellent reusability under ultraviolet (UV) irradiation. In this study, CoFe2O4/TiO2 were investigated as photocatalysts. green-synthesized before (recycled photocatalyst) using UV–visible spectroscopy, X-ray diffraction, transmission electron microscopy, scanning microscopy–energy dispersive fluorescence, Fourier transform infrared vibration sample magnetometry. optical bandgap energies formation 3.8 3.9 eV, respectively. typical organic pollutant methylene blue was completely degraded within 2 h with an 97.4% nanocomposites. crystallite sizes use 11.1 10.5 nm, magnetic hysteresis curve also showed that, use, had a saturation magnetization 10.6 emu/g coercivity 90 Oe. properties, crystal structures, morphologies indicated that same prepared retained ability use. Hence, it can be concluded deliver performance, we believe our findings provide new platform efficient
