Carbon Nanotubes Doped with 52 wt% Cobalt (Co) Nanopowder/Nanoparticles

Carbon nanotubes doped with 52 wt% cobalt (Co) nanoparticles unite the high electrical conductivity and mechanical resilience of MWCNTs with cobalt’s ferromagnetism and catalytic activity. The hybrid structure enables robust conductive networks, magnetic responsiveness, and enhanced durability, supported by high-purity constituents and stable dispersion potential. This makes CNT–Co composites a compelling choice for energy storage (anode/catalyst supports), high-frequency and EMI-sensitive electronics, magnetically assisted biosensing, and multifunctional composites where strength, conductivity, and processability must coexist.

Technical Properties

Applications

• Energy Storage: CNT–Co hybrids are used in lithium-ion battery electrodes and supercapacitor architectures, where CNT networks provide efficient electron transport and Co enhances redox activity, cycle stability, and rate performance. The magnetic and catalytic features also support hydrogen-related systems and advanced electrode manufacturing through improved dispersion and structural integrity.
• Electronics and Optoelectronics: They enable conductive and EMI-attenuating coatings, interconnects, and thin films for transistors and flat panel displays, leveraging CNT conductivity with Co’s magnetic loss mechanisms for electromagnetic shielding. In optoelectronic stacks and solar cells, the composite contributes to stable charge transport and thermal robustness under demanding operating conditions.
• Biomedical and Biosensing: In biosensors, CNT–Co materials deliver fast electron transfer and magnetically assisted analyte manipulation, improving sensitivity and signal fidelity. For drug delivery and nanoprobes, the hybrid’s functionalizable surfaces and magnetic response enable guided localization and controlled interactions, subject to appropriate biocompatibility and surface treatment.
• Composites and Structural Materials: As multifunctional fillers in polymer, ceramic, and metal matrices, CNT–Co hybrids raise tensile strength, hardness, elastic modulus, and electrical pathways. They are suited to aerospace, automotive, and protective systems where mechanical performance, conductivity, and magnetic features add value in lightweight designs.
• Catalysis and Environmental: They act as supports and active components in electrocatalysis and heterogeneous reactions (e.g., hydrogenation, oxygen reduction), benefiting from Co’s catalytic behavior and CNT’s high-surface conductive scaffolds. The composite also serves in gas-discharge tubes and electromagnetic absorption media, and can be tailored for pollutant adsorption and remediation tasks.
