ABSTRACT:
An economical method of preparing a large-sized graphene sheet having a desired thickness includes forming a film, the film comprising a graphitizing catalyst; heat-treating a gaseous carbon source in the presence of the graphitizing catalyst to form graphene; and cooling the graphene to form a graphene sheet. A graphene sheet prepared according to the disclosed method is also described.
