The effectiveness of photocatalytic degradation is a significant factor in addressing environmental pollution. This study examines the capability of a hybrid material consisting of FeFe oxide nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The synthesis of this composite material was conducted via a simple solvothermal 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 Fe3O4-SWCNT composite was assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.

The results demonstrate that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure Fe3O4 nanoparticles and SWCNTs alone. The enhanced performance 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 FeFe2O3-SWCNT composite holds possibility as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
