The performance of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study explores the capability 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 conducted via a simple hydrothermal method. The produced nanocomposite was evaluated using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The degradation efficiency of the FeFe oxide-SWCNT composite was determined 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 transfer and reduces electron-hole recombination. This study suggests that the FeFe2O3-SWCNT composite holds possibility as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
