The performance of photocatalytic degradation is a important factor in addressing environmental pollution. This study examines the ability of a combined material consisting of FeFe oxide nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The preparation of this composite material was conducted via a simple hydrothermal method. The resulting nanocomposite was characterized 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 evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
