The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study examines the ability of a composite material consisting of FeFe2O3 nanoparticles and single-walled carbon nanotubes (SWCNTs) here for enhanced photocatalytic degradation of organic pollutants. The synthesis of this composite material was carried out via a simple hydrothermal method. The produced nanocomposite was evaluated using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performance of the FeFe oxide-SWCNT composite was evaluated 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 degradation rate can be attributed to the synergistic effect between FeFe oxide nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds possibility as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
