The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study examines the potential of a hybrid 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 hydrothermal method. The produced 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 FeFe oxide-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.

The results reveal that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure Fe3O4 nanoparticles and SWCNTs alone. The enhanced efficiency can be attributed to the synergistic effect between FeFe oxide nanoparticles and SWCNTs, which promotes charge generation and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
