Blog Article
The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study examines the capability of a combined material consisting of FeFe2O3 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 hydrothermal method. The resulting nanocomposite was evaluated using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photocatalytic activity of the FeFe oxide-SWCNT composite was evaluated 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 FeFe oxide nanoparticles and SWCNTs, which promotes charge transfer and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a effective photocatalyst for the degradation of organic pollutants in wastewater treatment.
