The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study explores the potential of a combined 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 achieved 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 Fe3O4-SWCNT composite was assessed 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 FeFe2O3 nanoparticles and SWCNTs alone. The enhanced degradation rate can be attributed to the synergistic effect between FeFe oxide nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
