20100239489 | Methods for Controlling the Quality of Metal Nanocatalyst for Growing High Yield Carbon Nanotubes - Methods are provided for the preparation of single-walled carbon nanotubes using chemical vapor deposition processes. In some aspects, single-walled carbon nanotubes having narrow distribution of diameters are formed by contacting a carbon precursor gas with a catalyst on a support, wherein the catalyst has an average diameter of less than about 2 nm. | 09-23-2010 |
20120237436 | Catalyst For The Growth Of Carbon Single-Walled Nanotubes - Methods and processes for synthesizing single-wall carbon nanotubes are provided. A carbon precursor gas is contacted with metal catalysts deposited on a support material. The metal catalysts are preferably nanoparticles having diameters less than about 3 nm. The reaction temperature is selected such that it is near the eutectic point of the mixture of metal catalyst particles and carbon. Further, the rate at which hydrocarbons are fed into the reactor is equivalent to the rate at which the hydrocarbons react for given synthesis temperature. The methods produce carbon single-walled nanotubes having longer lengths. | 09-20-2012 |
