Abstract

This invention relates generally to a method for producing single-wall carbon nanotube (SWNT) catalyst supports and compositions thereof. In one embodiment, SWNTs or SWNT structures can be employed as the support material. A transition metal catalyst is added to the SWNT. In a preferred embodiment, the catalyst metal cluster is deposited on the open nanotube end by a docking process that insures optimum location for the subsequent growth reaction. The metal atoms may be subjected to reductive conditions.

Independent Claims | See all claims (18)

  1. 1. A method for producing a catalyst support comprising: (a) providing a plurality of single-wall carbon nanotubes; (b) contacting an end of at least some of the single-wall carbon nanotubes of the plurality with at least one catalytic metal, wherein the catalytic metal comprises a Group VI metal; and (c) activating the catalytic metal.
  2. 19. A composition comprising a catalytic metal supported on at least one single-wall carbon nanotube, wherein the catalytic metal is selected from the group consisting of chromium (Cr) and tungsten (W).
