The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study explores the ability of a hybrid material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The preparation of this composite material was carried out via a simple solvothermal method. The resulting nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performance of the FeFe oxide-SWCNT composite was assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results reveal that the FeFe2O3-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe2O3 nanoparticles and SWCNTs alone.
