The performance of photocatalytic degradation is a crucial factor in addressing graphene oxide nanoparticles environmental pollution. This study investigates the ability of a composite material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication of this composite material was conducted via a simple solvothermal method. The resulting nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photocatalytic activity of the FeFe2O3-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the FeFe oxide-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure Fe3O4 nanoparticles and SWCNTs alone. The enhanced degradation rate can be attributed to the synergistic effect between FeFe2O3 nanoparticles and SWCNTs, which promotes charge generation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds potential as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
