Abstract (en)

[origin: WO0149599A2] An improved vapor phase deposition method for preparation of single walled carbon nanotubes on an aerogel supported metal catalyst. The total yield of SWCNTs often is at least about 100 %, based the weight of the catalyst, for a reaction time of at least about 30 minutes.
