Carbon Nanotubes Doped with 50 wt% Iron Oxide (Fe3O4) Nanopowder/Nanoparticles

Description

Carbon Nanotubes Doped with 50 wt% Iron Oxide (Fe₃O₄) Nanopowder/Nanoparticles

This advanced nanocomposite integrates the unique structural and conductive properties of multi-walled carbon nanotubes (MWCNTs) with the magnetic, catalytic, and electrochemical characteristics of iron oxide (Fe₃O₄) nanoparticles. By doping CNTs with 50 wt% Fe₃O₄ nanopowder, the resulting material offers a powerful synergy that enhances both mechanical and functional performance across a wide range of applications.

The Fe₃O₄ nanoparticles are near-spherical, brown-colored, and average 30 nm in diameter. With a specific surface area of 45 m²/g and 99.9% purity, these nanoparticles contribute excellent magnetic responsiveness and catalytic activity. Combined with >97 wt% pure MWCNTs—featuring high surface area, low ash content, and strong electrical conductivity—this hybrid nanomaterial is engineered for performance.
