Carbon Nanotubes Doped with 32 wt% Iron (Fe) Nanopowder/Nanoparticles

Carbon Nanotubes doped with 32 wt% Iron nanoparticles combine CNTs’ high electrical conductivity and mechanical resilience with iron’s magnetic properties, catalytic activity, and structural reinforcement capacity. The irregular Fe nanoparticles (800 nm, 1–5 m²/g surface area, true density 8.1 g/cm³) are uniformly integrated into CNT networks, resulting in a hybrid composite with enhanced hardness, tensile strength, specific strength, and elastic modulus. This synergy provides multifunctional performance, making CNT–Fe hybrids suitable for energy storage, electronics, biomedical systems, catalysis, and advanced composites.

Applications

Energy & Storage: CNT–Fe hybrids are applied in lithium-ion batteries and supercapacitors where CNTs provide conductive pathways and iron enhances electrode stability, redox activity, and cycle life, while hybrid porosity also supports hydrogen storage and efficient charge transfer.
Electronics & Optoelectronics: These composites are used in transistors, flat panel displays, and solar cells, combining CNT conductivity with iron’s magnetic and catalytic properties to improve charge transport, optical performance, and thermal stability, while also supporting photoluminescence and template-based nanofabrication.
Biomedical & Biosensing: CNT–Fe hybrids are explored in biosensors for sensitive detection and in drug delivery systems where iron’s magnetic response and CNT’s functional surfaces enable controlled release, targeting, and nanoprobes for imaging and diagnostics.
Composites & Structural Materials: In polymer and ceramic composites, CNT–Fe hybrids improve tensile strength, hardness, and elastic modulus, making them suitable for aerospace, automotive, and construction applications requiring lightweight yet durable materials with added conductivity.
Catalysis & Environmental: They act as catalyst supports in electrochemical and photocatalytic reactions, leveraging iron’s catalytic activity and CNT’s conductive scaffolds, while also being used in gas-discharge tubes, pollutant remediation, and environmental sensing.
