    摘要： 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.

    摘要： Methods and processes for preparing supported metal catalysts are provided, where the supported metal catalysts can be used for the bulk synthesis of carbon nanotubes. The salts of the metal and the support are selected such that they are soluble in the same solvent. The catalyst can be prepared from the liquid phase through joint precipitation of the metal and the support material. The methods can be used to increase the metal load on the support. Use of the catalysts increases the yield of the carbon nanotubes.

    摘要： A method for treating carbon nanotubes with microwave energy to selective remove metallic-type carbon nanotubes is provided. A sample containing carbon nanotubes is positioned in a microwave cavity at a location corresponding to a maximum in the electric field component of a stationary wave having a microwave frequency. The sample is exposed to the microwave energy for a sufficient period of time to increase the proportion of semiconducting-type carbon nanotubes within the sample. Alternatively, a sample consisting essentially of metallic-type and semiconducting-type carbon nanotubes is exposed to microwave energy for a sufficient period of time to increase the proportion of semiconducting-type carbon nanotubes within the sample.
