摘要： Carbon nanotubes are formed by chemical vapor deposition using metal nanoparticles as a growth substrate. Control over the size and properties of the carbon nanotubes is achieved by controlling the size of the metal nanoparticles in the growth substrate. The metal nanoparticles of a controlled size may be formed by a thermal decomposition reaction of a metal salt in a passivating solvent.

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, processes, and apparatuses for the continuous synthesis of carbon nanostructures are provided. Metal catalysts having small diameter and narrow distribution of particle sizes are prepared and continuously injected as aerosols into a reactor. The metal catalysts are supported on supports that are substantially free of carbon. The metal catalyst, in the form of a powder, is placed on a fluidized bed and aerosolized using an inert gas. The powder entrailed in the gas is injected near the top of a vertical reactor for the synthesis of SWNTs.
