| 20100202958 | POROUS FILAMENTOUS NANOCARBON AND METHOD OF FORMING THE SAME - A method for forming a porous filamentous nanocarbon involves radially forming a tunnel-like mesopore from an outer periphery toward the central axis of a filamentous nano carbon by attaching a material having a metal catalyst on an outer periphery of the filamentous nanocarbon and removing a carbon hexagonal plane through gasification in virtue of the metal catalyst. | 08-12-2010 |
| 20090075077 | ULTRA-FINE FIBROUS CARBON AND PREPARATION METHOD THEREOF - The present invention discloses ultra-fine fibrous carbon and preparation of the same. Specifically, the present ultra-fine fibrous carbon is characterized by the graphite-like structure with the sp | 03-19-2009 |
| 20090004095 | Porous Filamentous Nanocarbon And Method Of Forming The Same - There is provided a porous filamentous nanocarbon and a method for forming the same. A mesopore formed on an outer periphery of the porous filamentous nanocarbon is a tunnel-like pore which is formed along the arrangement direction of the carbon hexagonal plane from the outer periphery toward a fiber axis. The porous filamentous nanocarbon is fabricated by selectively removing the carbon hexagonal plane constituting the filamentous nanocarbon through gasification in virtue of a catalyst, after highly dispersing Fe, Ni, Co, Pt, etc., of which size is 2-30 nm, on the surface of the filamentous nanocarbon. That is, the tunnel-like mesopore is formed radially by nano-drilling process. The size of the porous filamentous nanocarbon can be controlled according to the size of the nano-drilling catalyst and non-drilling conditions. | 01-01-2009 |
