PROCESS FOR PREPARING GRAPHENE SHELL AND GRAPHENE SHELL OBTAINED BY SAME PROCESS

摘要

Provided are a grapheme shell-preparing process capable of effectively controlling thickness of the grapheme shell, and a grapheme shell which is prepared by the grapheme shell-preparing process and can be used very effectively in hydrogen storages, optical fibers, conductive agents, minute reactants, drug carriers, and the like. A process of preparing a grapheme comprises the steps of: subjecting a solid-shaped graphitization catalyst to a first heat treatment in an organic solvent; carburizing the solid-shaped graphitization catalyst; subjecting the solid-shaped graphitization catalyst to a second heat treatment in an inert or reductive atmosphere; and forming a grapheme on the surface of the solid-shaped graphitization catalyst.
