The effectiveness of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the potential of a composite 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 achieved via a simple solvothermal method. The resulting 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 FeFe oxide-SWCNT composite was assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results demonstrate that the FeFe oxide-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe2O3 nanoparticles and SWCNTs alone. The enhanced degradation rate can be attributed to the synergistic effect between FeFe2O3 nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the FeFe2O3-SWCNT composite holds potential as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
