The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the capability of a composite material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The preparation of this composite material was achieved via a simple solvothermal method. The resulting nanocomposite was evaluated using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), nano titanium dioxide and transmission electron microscopy (TEM). The degradation efficiency of the FeFe2O3-SWCNT composite was assessed 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 efficiency can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds possibility as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
