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.

L'invention concerne un nanocarbone filamenteux poreux et son procédé de formation. Un mésopore formé sur la périphérie du nanocarbone filamenteux poreux est un pore du type tunnel qui est formé dans le sens d'agencement d'un plan hexagonal de carbone de la périphérie vers un axe de fibre. Ledit nanocarbone filamenteux poreux est produit par retrait sélectif du plan hexagonal de carbone constituant le nanocarbone filamenteux via une gazéification au moyen d'un catalyseur, après dispersion élevée de Fe, Ni, Co, Pt, etc. dont la taille est comprise entre 2 et 30 nm, sur la surface du nanocarbone filamenteux. Le mésopore du type tunnel est formé radialement au moyen d'un processus de nano-forage. La taille du nanocarbone filamenteux poreux peut être régulée en fonction de la taille du catalyseur de nano-forage et des conditions de nano-forage.
