Abstract:
1. A process for producing catalyst body for production of brush-shaped carbon nanostructure, comprising the steps of forming a reaction preventive layer consisting of oxides on the surface of a substrate by heating-treating said substrate, forming a catalyst metal layer on the surface of said reaction preventive layer, forming an aggregation suppressive layer consisting of metal oxide on the surface of said catalyst metal layer by heat-treating in a temperature range of 80-800° C., granulating uniformly a catalyst layer consisting of said catalyst metal layer and said aggregation suppressive layer by heating at a temperature increase rate equal to or of more than 10° C./sec; and forming a catalyst particle layer consisting of metallic catalyst particles whose main constituent is a catalyst metal on the surface of said reaction preventive layer.
