Abstract

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 se¬ lectively 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 nano-drilling conditions.
