The efficacy of photocatalytic degradation is a significant factor in addressing environmental pollution. This study investigates the ability of a combined material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The preparation of this composite material was achieved via a simple solvothermal method. The obtained nanocomposite was characterized 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 reveal that the FeFe2O3-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide 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 FeFe oxide-SWCNT composite holds potential as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
