Abstract
The escalating issue of phenol dye-containing wastewater necessitates the development of efficient and sustainable treatment methods. In this context, we present a novel composite photocatalyst comprising ZnFe2O4 (ZFO) nanoparticles supported on nanocellulose(NC), aimed at addressing this environmental challenge. The synthesis involved a facile hydrothermal method followed by impregnation of ZFO nanoparticles onto the NC matrix. ZFO, as a weakly magnetic semiconductor catalytic material, was utilized in photocatalytic experiments under magnetic field conditions. By controlling the electron spin states through the magnetic field, electron-hole recombination was suppressed, resulting in improved photocatalytic performance.The resultant composite exhibited remarkable photocatalytic activity under visible light irradiation, owing to the synergistic effect between ZFO nanoparticles and NC. Through systematic evaluation, we demonstrated the high efficiency and stability of the composite photocatalyst in degrading phenol dye pollutants in aqueous solutions. Furthermore, the composite material exhibited promising recyclability, retaining its activity even after multiple usage cycles. This study underscores the potential of the ZFO/NC composite for sustainable wastewater treatment, offering a promising avenue for environmental remediation.
