The efficacy of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study explores the potential of a hybrid material consisting of FeFe oxide 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 chemical method. The resulting nanocomposite was characterized using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalytic performance of the FeFe2O3-SWCNT composite was assessed by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results reveal that the FeFe oxide-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe2O3 nanoparticles and SWCNTs alone. The enhanced performance 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 FeFe oxide-SWCNT composite holds promise as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
