The efficacy of photocatalytic degradation palladium nanoparticles is a important factor in addressing environmental pollution. This study investigates the ability 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 carried out via a simple hydrothermal 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 Fe3O4-SWCNT composite was assessed 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.
