Method for producing hydrogen occlusion material

Abstract

A hydrogen occlusion material producing method capable of producing a hydrogen occlusion material during preparation of a carbonaceous material such as carbon nanotubes or the like. A gas atmosphere at a predetermined pressure is formed in a chamber and then a DC current is fed to a pair of carbon electrodes from a discharge power unit while keeping the carbon electrodes spaced from each other at a predetermined interval through a pair of position control units, leading to arc discharge. This results in an anode constituted by platinum metal which exhibits both a catalytic function during preparation of carbon nanotubes and a function of dissociating hydrogen molecules into hydrogen atoms being heated, to thereby produce soot. The soot contains a large amount of hydrogen occlusion material wherein fine particles of the platinum metal are uniformly adhered to single-layer carbon nanotubes, resulting in being used for a hydrogen occlusion material.
