In this study, we present a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) modified with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The preparation process involves a two-step approach, first immobilizing SWCNTs onto a suitable substrate and then incorporating Fe3O4 nanoparticles via a solvothermal method
