The effectiveness of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study investigates the ability of a combined material consisting of FeFe2O3 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 solvothermal method. The resulting nanocomposite was evaluated 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 evaluated by monitoring the degradation of methylene blue (MB) under UV irradiation.
The results demonstrate that the FeFe2O3-SWCNT composite exhibits significantly higher photocatalytic activity compared to pure FeFe2O3 nanoparticles and SWCNTs alone. The enhanced efficiency can be attributed to the synergistic effect between FeFe2O3 nanoparticles and SWCNTs, which promotes charge generation and reduces electron-hole recombination. This study suggests that the FeFe2O3-SWCNT composite holds promise as a superior photocatalyst for the degradation of organic pollutants in wastewater treatment.
