The effectiveness of photocatalytic degradation is a significant factor in addressing environmental pollution. This study explores the ability of a hybrid material consisting of FeFe2O3 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 hydrothermal 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 FeFe oxide-SWCNT composite was evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the FeFe oxide-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe oxide nanoparticles and SWCNTs alone. The enhanced performance can be attributed to the synergistic effect between FeFe oxide nanoparticles and SWCNTs, which promotes charge separation and reduces electron-hole recombination. This study suggests that the FeFe2O3-SWCNT composite holds potential as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
