摘要： A method for producing carbon nanotubes by contacting a carbon containing gas with metallic catalytic particles. The catalytic particles contain at least one metal from Group VIII, including for example Co, Ni, Ru, Rh, Pd, Ir, and Pt, and at least one metal from Group VIb including for example Mo, W and Cr. The metal component may be deposited on a support. Preferably, a substantial percentage of the nanotubes formed are single-walled carbon nanotubes. Further, a method for determining catalyst composition and reaction conditions for optimizing production of single-walled carbon nanotubes is also disclosed.

摘要： This invention relates to a process for the preparation of a substrate-free aligned nanotube film, comprising: (a) synthesizing a layer of aligned carbon nanotubes on a quartz glass substrate by pyrolysis of a carbon-containing material, in the presence of a suitable catalyst for nanotube formation; and (b) etching the quartz glass substrate at the nanotube/substrate interface to release the layer of aligned nanotubes from the substrate. The invention also provides a process for the preparation of a multilayer carbon nanotube film comprising depositing a substrate-free carbon nanotube film onto another nanotube film. Further, the invention provides a process for the preparation of a “hetero-structured” multilayer carbon nanotube film which includes one or more carbon nanotube layers together with layers of other materials, such as metal, semiconductor and polymer.

摘要： This invention relates generally to a method for growing single-wall carbon nanotube (SWNT) from seed molecules. The supported or unsupported SWNT seed materials can be combined with a suitable growth catalyst by opening SWNT molecule ends and depositing a metal atom cluster. In one embodiment, a suspension of seed particles containing attached catalysts is injected into an evaporation zone to provide an entrained reactive nanoparticle. A carbonaceous feedstock gas is then introduced into the nanoparticle stream under conditions to grow single-wall carbon nanotubes. Recovery of the product produced can be done by filtration, centrifugation and the like.

摘要： The temperature of a catalyst is heated to 535° C. with an electric furnace for feeding hydrogen gas into a reaction tube at a flow rate of 50 cc/min. for two hours and reducing the catalyst, and thereafter reaction gas containing hydrogen and carbon dioxide in a mixing ratio of 2:1 is fed into the reaction tube. The carbon dioxide contained in the reaction gas is reduced with hydrogen by coming into contact with the catalyst, and carbon such as carbon nanotube is precipitated on the surface of the catalyst. The carbon nanotube or the like can be produced under a lower temperature and ordinary pressure with no requirement for a specific apparatus for high-temperature and high-pressure reaction.
