Blog Article
The efficacy of photocatalytic degradation is a important factor in addressing environmental pollution. This study investigates the potential of a hybrid material consisting of Fe3O4 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 produced nanocomposite was analyzed using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The degradation efficiency of the FeFe2O3-SWCNT composite was determined by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results indicate that the FeFe2O3-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 transfer and reduces electron-hole recombination. This study suggests that the FeFe oxide-SWCNT composite holds possibility as a efficient photocatalyst for the degradation of organic pollutants in wastewater treatment.
