Provided are a process for economically preparing a graphene shell having a desired configuration which is applicable in various fields wherein in the process the thickness of the graphene shell can be controlled, and a graphene shell prepared by the process.
Claims18
A process of preparing a graphene shell, the process comprising:
- forming a graphitizing catalyst in a three-dimensional form;
- coating a polymer on the graphitizing catalyst;
- heat-treating the polymer coated on the graphitizing catalyst in an inert or reductive atmosphere to form a graphene shell;
- and
- further comprising separating the graphene shell by removing the graphitizing catalyst with an acid-treatment after the heat-treatment.
