摘要: The present invention relates to carbon materials comprising carbon nanotubes, powders comprising carbon nanotubes and methods of making carbon nanotubes. In the methods of the present invention, the size and/or formation of floating catalyst particles is closely controlled. The resulting carbon nanotubes typically exhibit armchair chirality and typically have metallic properties. The carbon nanotubes produced by this method readily form bulk materials, which typically have a conductivity of at least 0.7×106 Sm″1 in at least one direction. The invention has particular application to the manufacture of components such as electrical conductors. Suitable electrical conductors include wires (e.g. for electrical motors) and cables (e.g. for transmitting electrical power).

摘要: The present invention relates to the technical field of nanometer materials, which discloses a composite material of metal foam-carbon nanotube, the preparation method, and the use thereof. The preparation method of the present invention is: pre-treating a substrate of polyurethane sponge, then placing the pre-treated substrate of polyurethane sponge into a electroless plating solution containing metallic element to carry on a electroless plating reaction, and drying to obtain a metal foam catalyst on the polyurethane sponge substrate; then placing the metal foam catalyst into a tube furnace and raising the temperature to 500˜550° C.; introducing hydrogen and maintaining for 0.5 to 2 hour; then raising the temperature to 600˜800° C. and introducing an acetylenemixture gas as a carbon source, thus the target product is obtained as the carbon nanotubes growing on the surface of the metal foam catalyst by chemical vapor deposition. The prepared carbon nano-fibers or carbon nano-tubes are in situ formed on the transition metal catalyst surface. The metal/carbon interface is firmly bonded; the prepared carbon nano-fibers or carbon nano-tube are with good dispersity and their diameters are controllable and uniform.

摘要: Techniques and methods are disclosed for producing a plurality of nanoparticles that can be used as catalysts to grow carbon or boron nitride nanotubes. The method includes mixing an iron salt including a ferrous or ferric ion with a long chain amine, thiol or polyphenol in a solvent comprising alcohol to produce a solution. Ferric or ferrous ion is reduced to zero valence iron. Nucleation of iron nanoparticles is initialized. The iron nanoparticles are capped to retard nanoparticle growth. The nanoparticles include an elemental iron core coated with a polyphenol that isolates the core from oxygen. The nanoparticles include an average diameter of less than or equal to 15.8 nanometers. The iron core may further include a secondary metal to form an iron-alloy. The secondary metal, in some applications, can be a transition metal.
