The effectiveness of photocatalytic degradation is a important factor in addressing environmental pollution. This study explores the capability of a combined 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 carried out via a simple chemical method. The produced 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 reveal that the FeFe2O3-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide nanoparticles and SWCNTs alone. The enhanced degradation rate can be attributed to the synergistic effect between Fe3O4 nanoparticles and SWCNTs, which promotes charge generation and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
