The efficacy of photocatalytic degradation is a important factor in addressing environmental pollution. This study investigates the capability of a combined material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication of this composite material was achieved via a simple solvothermal method. The produced 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 demonstrate that the FeFe2O3-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.
