摘要
The effect of gas adsorption on different carbon nanotube systems is studied using ESR spectrosocpy. One system consists of purified and unpurified single-walled carbon nanotubes, one of unpurified multiwalled tubes, and one of multi-walled tubes where defects have been introduced purposefully at different levels. In single- and multi-walled tubes, hydrogen adsorbs preferentially on defects. Electron-donating ammonia seems to affect the interlayer interaction in multi-walled carbon nanotubes.
