Nitrogen-doped Multi Walled Carbon Nanotubes

Description

Nitrogen-Doped Multi-Walled Carbon Nanotubes (N-MWCNTs)

Purity: >98 wt% | Nitrogen Content: 3–5 wt% | Surface Area: 100 m²/g

Nitrogen-doped Multi-Walled Carbon Nanotubes (N-MWCNTs) are advanced nanomaterials that combine the high electrical conductivity and mechanical strength of conventional carbon nanotubes with the enhanced surface chemistry provided by nitrogen incorporation. Produced via CVD (Chemical Vapor Deposition), these nanotubes exhibit improved reactivity, wettability, catalytic activity, and electron-donor properties—making them ideal for energy, biomedical, catalytic, and sensing applications.

Nitrogen atoms integrated into the graphitic lattice introduce defect sites and functional groups that significantly enhance their performance in electrochemical and electronic environments. This makes N-MWCNTs particularly suitable for next-generation supercapacitors, batteries, fuel cells, and targeted drug delivery systems.
