The effectiveness of photocatalytic degradation is a crucial factor in addressing environmental pollution. This study explores the ability of a hybrid material consisting of Fe3O4 nanoparticles and single-walled carbon nanotubes (SWCNTs) for enhanced photocatalytic degradation of organic pollutants.
