Nitrogen Doped Graphitized Multi-walled Carbon Nanotubes
1. Outer diameter: 10-30nm,30-60nm,60-100nm
2. Length: long tube 5-20um and short tube 1-2um
3. Purity: 99%
Electrode materials nitrogen doped MWCNTs:
1. Heterogeneity elemental nitrogen-doped carbon
nanotubes can be effective in controlling the crystal structure and the
electronic structure of carbon nanotubes to produce superior physical and
chemical properties of pure carbon nanotubes.
2. Nitrogen atoms doped carbon nanotubes can
cause distortion of the hexagonal topology, so as to increase the concentration
of nitrogen-doped carbon nanotubes become bent by the relatively flat, while
the increase is better than the defective wall roughened. Doping nitrogen atom
reduces the thermal stability of the obtained product.
3. Carbon nanotubes electrode stability, high
efficiency, with better response rates at high current, is a more superior
supercapacitor electrode material. Nitrogen doping reduces the contact
resistance and equivalent series resistance of carbon nanotubes electrodes,
increase the frequency response.
4 nitrogen atoms doped carbon nanotubes changes
polarity, making it easier to infiltrate the electrolyte in the carbon nanotube
networks, improved electrochemical properties that have a good effect.
