摘要： Developed is high-efficiency synthesis method and apparatus capable of promoting the initial growth of carbon nanostructure by eliminating the initial fluctuation time and rising time in raw gas flow quantity.
A high-efficiency synthesis method of carbon nanostructure according to the present invention is a high-efficiency synthesis method of carbon nanostructure, the method comprising: bringing raw material gas and a catalyst into contact with each other under reactive conditions so as to produce a carbon nanostructure, wherein: the initiation of contact of the raw material gas with the catalyst is carried out instantaneously. Reaction conditions such as temperature and raw material gas concentration are set so as to meet those for catalyst growth, and under the reaction conditions, the initiation of contact of raw material gas G with catalyst 6 is carried out instantaneously. Consequently, the initial growth of carbon nanostructure is positively carried out, and the height growth and thickness growth thereof can be effected in high efficiency. Further, high-density growth and short-time high-speed growth can be realized. The catalyst includes any forms of catalyst such as catalyst substrate, catalyst structure, catalyst powders and catalyst pellet. It is especially preferred to employ a system wherein the feed and interruption of the raw material gas G are intermittently controlled by means of an electromagnetic three-way valve 24.

摘要： A catalyst for preparing a carbon nanocoil which comprises a carbide catalyst comprising the elements of (transition metal element, In, C) or (transition metal element, Sn, C), or comprises a metal catalyst comprising the elements of (Fe, Al, Sn) or (Fe, Cr, Sn). The transition metal element of the carbide catalyst is preferably Fe, Co or Ni. More preferable catalysts include Fe3InC0.5, Fe3InC0.5Snw and Fe3SnC. A catalyst comprising a porous carrier and the above catalyst carried thereon is capable of controlling the diameters of the wire and the coil of the resulting carbon nanocoil. The above catalyst allows the preparation of a carbon nanocoil with high efficiency, and it has been found through taking the catalyst nucleus attached on the apex of a carbon nanocoil as a true catalyst for preparing the carbon nanocoil and determining the structure of the catalyst nucleus.

摘要： A method for synthesizing carbon nanocoils with high efficiency, by determining the structure of carbon nuclei that have been attached to the ends of carbon nanocoils and thus specifying a true catalyst for synthesizing carbon nanocoils is implemented. The catalyst for synthesizing carbon nanocoils according to the present invention is a carbide catalyst that contains at least elements (a transition metal element, In, C) or (a transition metal element, Sn, C), and in particular, it is preferable for the transition metal element to be Fe, Co or Ni. In addition to this carbide catalyst, a metal catalyst of (Fe, Al, Sn) and (Fe, Cr, Sn) are effective. From among these, catalysts such as Fe 3 InC 0.5 , Fe 3 InC 0.5 Snw and Fe 3 SnC are particularly preferable. The wire diameter and the coil diameter can be controlled by using a catalyst where any of these catalysts is carried by a porous carrier.

摘要： It is the purpose of this invention to present a process for producing carbon nanostructure in which the mechanism of continuous carbon nanostructure growth can be optimized and a high-quality carbon nanostructure can be produced, a catalyst for carbon nanostructure growth which is for use in the production, a raw-material gas and a carrier gas for producing the same, and an apparatus for producing the same. The process for carbon nanostructure production, in which the length of the nanostructure can be continuously controlled comprises feeding a carrier gas and a raw-material gas to a reaction chamber (4) to produce a carbon nanostructure (2) with a catalytic structure (6), wherein the concentrations of oxidation gases contained in the carrier gas and raw-material gas, such as oxygen and water (in the case of raw-material acetylene gas, minor ingredients such as DMF and acetone, which are solvents), are regulated to a moderate value. Thus, a carbon nanostructure of good quality can be produced at a high efficiency.
