Title:
METHOD FOR PRODUCTION OF CUP-SHAPED NANOCARBON AND CUP-SHAPED NANOCARBON
Document Type and Number:
WIPO Patent Application WO/2008/004347
Kind Code:
A1
Abstract:
Disclosed is a method for production of a cup-shaped nanocarbon comprising a Graphene sheet. The nanocarbon molecule has a cup-like shape wherein the bottom part and the top part are opened. The method comprises the following steps (A) and (B): (A) providing a cupstack-type carbon nanotube composed of laminated cup-shaped nanocarbons, wherein both of the bottom part and the top part of each of the cup-shaped nanocarbons are opened; and (B) treating the cupstack-type carbon nanotube with a reducing agent to separate each of the cup-shaped nanocarbons from the cupstack-type carbon nanotube.
