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