The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the capability of a combined material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The synthesis of this composite material was conducted 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 catalytic performance of the FeFe2O3-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 Fe3O4 nanoparticles and SWCNTs alone.
