Blog Article
The effectiveness of photocatalytic degradation is a significant factor in addressing environmental pollution. This study explores the potential of a hybrid material consisting of Fe3O4 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 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 degradation efficiency of the FeFe oxide-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the Fe3O4-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe2O3 nanoparticles and SWCNTs alone. The enhanced degradation rate 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.
