  • SYNTHESIS OF SMALL AND NARROW DIAMETER DISTRIBUTED CARBON SINGLE WALLED NANOTUBES
    Publication number: 20180029888
    Abstract: Method and processes for synthesizing single-wall carbon nanotubes is 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 50 nm. The reaction temperature is selected such that it is near the eutectic point of the mixture of metal catalyst particles and carbon.

  • Methods for controlling the quality of metal nanocatalyst for growing high yield carbon nanotubes
    Patent number: 8012447
    Abstract: 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.

  • Methods for determining particle size of metal nanocatalyst for growing carbon nanotubes
    Patent number: 7719265
    Abstract: Methods and processes for determining the particle size distribution of metal catalysts are provides. Superconducting Quantum Interference Device (SQUID) magnetometer is used to evaluate the magnetic catalyst particle sizes dispersed in the support material. Dependence on variation of the metal/support material ratio, which defines the metal particle sizes, the catalyst can show paramagnetic, superparamagnetic, and ferromagnetic behaviors.

  • Catalyst for synthesis of carbon single-walled nanotubes
    Patent number: 7485600
    Abstract: 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.
