The effectiveness of photocatalytic degradation is a significant factor in addressing environmental pollution. This study investigates the potential 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 achieved via a simple solvothermal method. The resulting nanocomposite was characterized using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photocatalytic activity of the FeFe oxide-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results demonstrate that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide nanoparticles and SWCNTs alone. The enhanced performance can be attributed to the synergistic effect between FeFe2O3 nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
