The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the ability 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 achieved via a simple chemical method. The obtained 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 FeFe oxide-SWCNT composite was determined by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide nanoparticles and SWCNTs alone. The enhanced degradation rate can be attributed to the synergistic effect between FeFe oxide nanoparticles and SWCNTs, which promotes charge transfer and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
