The effectiveness of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the potential of a composite material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation ag nanoparticles of organic pollutants. The fabrication of this composite material was conducted via a simple chemical method. The resulting 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 FeFe oxide-SWCNT composite was assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide nanoparticles and SWCNTs alone.
