Graphene, device for producing graphene, and method for producing graphene
View Patent ↗A method for producing graphene includes: a pretreatment process of drying and pulverizing a vegetable material to obtain a carbon source; a carbonization process of carbonizing the carbon source to obtain a carbide; and a purification process of removing an impurity containing silica from the carbide obtained in the carbonization process, wherein the carbonization process including a heating process of supplying an inert gas into a chamber and heating the carbon source in the chamber in a plasma atmosphere.
1. A method for producing graphene comprising:
pretreating comprising drying and pulverizing a vegetable material to obtain a carbon source; and
carbonizing the carbon source to obtain graphene,
wherein the carbonizing comprises supplying the carbon source, supplying a halide, and heating the carbon source at a temperature of 400° C. or higher and 900° C. or lower, and
wherein the vegetable material contains 13% or more and 35% or less of silicon.
