Blog Article
The efficacy of photocatalytic degradation is a important factor in addressing environmental pollution. This study explores the potential of a composite material consisting of FeFe oxide nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants. The fabrication of this composite material was conducted via a simple chemical method. The produced nanocomposite was analyzed 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 evaluated 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 Fe3O4 nanoparticles and SWCNTs alone. The enhanced performance can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the Fe3O4-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
