Carbon nanostructure, and method and apparatus for manufacturing carbon nanostructure

摘要

A method for manufacturing a carbon nanostructure according to the present invention includes a preparation step of preparing a base body, an oxidization step and a step of growing a carbon nanostructure. In the step of preparing a base body, a base body with at least a part of a contact portion or an integral portion of a catalyst member and a separation member having been oxidized is prepared. In the step of growing a carbon nanostructure, a carbon nanostructure is grown in a separation interface region between the catalyst member and the separation member. The step of growing a carbon nanostructure includes at least one of a step of locally supplying a source gas to a portion of the catalyst member facing the separation interface region where the carbon nanostructure is being grown, and a step of locally heating the separation interface region.

主权项

1. A method for manufacturing a carbon nanostructure, comprising the steps of:
preparing a base body formed of a catalyst member including a catalyst and a separation member that are integral with each other, at least a part of an integral portion of said catalyst member and said separation member having been oxidized; and growing a carbon nanostructure in a fracture interface region between said catalyst member and said separation member, by heating said base body with said separation member being separated from said catalyst member while supplying a source gas containing carbon to said base body, said step of growing a carbon nanostructure including at least one of a step of locally supplying said source gas to a portion of said catalyst member facing said fracture interface region where said carbon nanostructure is being grown, and a step of locally heating said fracture interface region.
