  • Method for producing carbon material using catalyst, and carbon material
    Patent number: 9523163
    Abstract: Provided is a method for producing a carbon material, the method utilizing a cellulosic material and enables the carbon material, which retains the shape of the cellulosic material, to be produced in high yield. The method for producing a carbon material is characterized by comprising the steps of: allowing a cellulosic material and/or a regenerated cellulosic material to adsorb a sulfonic acid; and heating the cellulosic material and/or the regenerated cellulosic material which has adsorbed the sulfonic acid at a temperature of 600-2800° C. in an inert gas atmosphere.
    Type: Grant
