NANOTUBE-NANOHORN COMPOSITE AND PROCESS FOR PRODUCTION THEREOF

摘要

Provided is a nanotube-nanohorn composite which has both an aspect ratio higher than that of conventional nanohorns and high dispersibility and which enables the growth of diameter -controlled carbon nanotubes.  The nanotube-nanohorn composite is characterized by being provided with both carbon nanohorns and catalyst fine particles carried inside the carbon nanohorns, and is characterized in that each carbon nanohorn has an opening, that each catalyst fine particle is bogged and immobilized in the opening in such a way that part of the catalyst fine particle is exposed to the outside of the carbon nanohorn, and that the composite is further provided with carbon nanotubes grown from the catalyst fine particles.
