The efficacy of photocatalytic degradation is a significant factor in addressing environmental pollution. This study explores the capability of a composite material consisting of Fe3O4 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 hydrothermal method. The obtained 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 assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the FeFe oxide-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 generation and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds potential as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
