The performance of photocatalytic degradation is a significant factor in addressing environmental pollution. This study investigates 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 fabrication of this composite material was carried out via a simple solvothermal method. The obtained 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 FeFe2O3-SWCNT composite was determined 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 FeFe oxide nanoparticles and SWCNTs alone. The enhanced performance can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge generation 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.
