The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study investigates the capability of a hybrid material consisting of FeFe2O3 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 chemical method. The resulting nanocomposite was analyzed 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 FeFe2O3-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 FeFe2O3 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.
