The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study examines the capability of a combined material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication of this composite material was carried out via a simple chemical method. The resulting 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 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 FeFe oxide nanoparticles and SWCNTs alone. The enhanced performance 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 FeFe2O3-SWCNT composite holds possibility as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
