What is Carbon Nanotubes Doped with 12 wt% Iron (Fe) Nanopowder/Nanoparticles?

Carbon Nanotubes (CNTs) doped with 12 wt% Iron (Fe) refer to multi-walled or single-walled carbon nanotubes infused with iron nanoparticles at a concentration of 12 weight percent. The iron acts as a catalyst or functional agent, significantly enhancing magnetic, catalytic, and electrical properties of the CNTs.
