Title:
CATALYST MATERIAL
Document Type and Number:
Japanese Patent JPS61118140
Kind Code:
A
Abstract:

PURPOSE: To enhance the effect on preventing the cohesion of metallic particles by providing a layer which is periodically charged positively and negatively in the form of an intergraphitic compd. to specified neutral carbon, and then bringing the material into contact with ions contg. a catalytic metallic element.

CONSTITUTION: A layer which is periodically charged positively and negatively is provided to electrically neutral carbon obtained by applying a hardly graphitizing treatment in the form of an intergraphitic compd., the material is brought into contact with ions cong. a catalytic metallic element to grow the catalytic metallic element and its particles from the surface of the hardly graphitizable carbon, and a catalyst material is obtained. Meanwhile, a layer which is periodically charged positively and negatively is provided in the form of an intergraphitic compd. in the direction parallel to the C-axis of the graphite of electrically neutral and easily graphtizable carbon fibers which are already graphitized. Then the material is brought into contact with ions contg. a cata lytic metallic element to grow the catalytic metallic element and its particles from the surface of the carbon fiber, and a highly corrosion-resistant catalyst material is obtained.
