Carbonaceous nanotube, nanotube aggregate, method for manufacturing a carbonaceous nanotube

摘要

A carbonaceous nanotube has a hollow part with an inner diameter of, at most, 5 nm, and a thickness part of, at most, 10 nm. The thickness part is formed of carbon atoms and hydrogen atoms, optionally containing at least one transition metal atom. Such a carbonaceous nanotube has excellent conductivity and excellent wettability.
