The performance of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study examines the ability of a hybrid material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The preparation of this composite material was achieved via a simple chemical method. The obtained 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 Fe3O4-SWCNT composite was determined 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 FeFe oxide nanoparticles and SWCNTs alone. The enhanced efficiency can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge transfer and reduces electron-hole recombination. This study suggests that the FeFe2O3-SWCNT composite holds promise as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
