The efficacy of photocatalytic degradation is a important factor in addressing environmental pollution. This study examines the capability of a hybrid material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The synthesis of this composite material was carried out via a simple hydrothermal method. The obtained nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron here 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 Fe3O4-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 transfer and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
