METHOD FOR PRODUCING FIBROUS CARBONACEOUS NANO- MATERIAL AND ELECTROLYTIC MATERIAL USING THE SAME AND USED FOR ELECTROCHEMICAL CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fibrous carbonaceous nano- material which is used an electrolytic material for electrochemical capacitors or the like, and to provide the electrolytic material for the electrochemical capacitors. SOLUTION: This method for producing the fibrous carbonaceous nano- material having an accordion shape structure comprises kneading iron oxide (γ-ferrite) produced by a colloid dispersion method and lyophilized and having an average particle diameter of 20 to 80 nm and nickel particles produced by a precipitation method in an iron oxide/nickel particle weight ratio of 6/4 to 9/1, reducing the product in a reducing atmosphere at 400 to 700 deg.C, and then mixing carbon monoxide and/or a hydrocarbon as raw material gases with hydrogen gas on the surface of the mobile phase and/or fixed phase catalyst to subject the mixture to a gas phase decomposition reaction on the surface of the catalyst. And the electrolytic material for the electrochemical capacitors is provided.
