Abstract
It is intended to highly efficiently produce a high-density brush shaped carbon nanostructure useful in the production of CNT assembly, such as rope-shaped CNTs, and provide a catalyst body for production of brush-shaped carbon nanostructure that enables the production. The catalyst body for production of brush-shaped carbon nanostructure is one comprising a substrate (), an aggregation suppressive layer () superimposed on a surface thereof and a catalyst layer superimposed on the aggregation suppressive layer (). The catalyst layer is a catalyst particle layer () consisting of metallic catalyst particles () composed mainly of a catalytic metal. The metallic catalyst particles () have an average particle diameter, D, satisfying the relationship 0.5 nm≦D≦80 nm, and individual particles of the metallic catalyst particles () have a diameter, d, falling within the range of the above average particle diameter (D). Further, there are disclosed a process for producing the catalyst body, a brush-shaped carbon nanostructure and a process for producing the same.
