The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the potential fe3o4 of a combined material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The synthesis of this composite material was achieved via a simple chemical method. The obtained nanocomposite was characterized using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performance of the Fe3O4-SWCNT composite was determined by monitoring the degradation of methylene blue (MB) under UV irradiation.

The results demonstrate that the Fe3O4-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 Fe3O4 nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds potential as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
