Gas adsorption on carbon nanotubes


1. Single-Walled Carbon Nanotubes

1. Discovered in 1993 by S. Iijima

2. Single layer graphene sheet wrapped into a tubule and capped by half fullerenes

3. Diameter ~ 1nm

4. Length - up to several microns

5. Form carbon nanotube bundles consisting, typically,  30 to 100 tubes

2. Multi-walled Carbon Nanotubes

1. Discovered in 1991 by S. Iijima

2. Several coaxial tubes (in russian doll configuration)

3. Outer Diameter - ~2.5 - 30 nm

4. Length - from several nanometers up to several micrometers

3. Potential sites available for gas adsorption on single-walled carbon nanotube bundles

Inside surface of a tube is available only if the cap has been removed.

4. Possible adsorption phases on single-walled carbon nanotube bundles

* Our experiments show that no gas adsorption occurs in the interstitial channels for any atom greater than neon
