発明の名称 (英語) High-efficiency synthetic method for carbon nanostructure, apparatus and carbon nanostructure
発明の概要(英語) A high-efficient synthetic method and apparatus capable of accelerating the initial growth of carbon nanostructure by eliminating the initial fluctuation time and rising time of raw gas flow rate.
In particular, a method of synthesizing a carbon nanostructure in high efficiency, comprising bringing a raw gas into contact with a catalyst under reactive conditions so as to obtain a carbon nanostructure, wherein the initiation of contact of the raw gas with the catalyst is carried out instantaneously.
Reaction conditions such as temperature and raw gas concentration are set so as to meet those for catalyst growth, and under the reaction conditions, the initiation of contact of raw 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 comprehends those of arbitrary configurations such as catalyst plate, catalyst structure, catalyst powder and catalyst pellet.
It is especially preferred to employ a system wherein the supply and cut of raw gas (G) are intermittently controlled by means of electromagnetic three-way valve (24).
