The efficacy of photocatalytic degradation is a significant factor in addressing environmental pollution. This study examines the ability of a composite material consisting of FeFe oxide nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants.
