The efficacy of photocatalytic degradation is a important factor in addressing environmental pollution. This study explores the capability 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 chemical method. The resulting nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The degradation efficiency of the FeFe2O3-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.

The results demonstrate that the FeFe oxide-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure Fe3O4 nanoparticles and SWCNTs alone.
