The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study examines the potential of a hybrid material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication 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 degradation efficiency of the Fe3O4-SWCNT composite was evaluated 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. The enhanced efficiency can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge transfer and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
