    摘要: Provided are a method of preparing a graphene shell and a graphene shell prepared using the method. A first heat treatment is performed on a mixture of an organic solvent and a graphitization catalyst so as to carburize the graphitization catalyst with carbon decomposed from the organic solvent. The graphitization catalyst is in the form of particles. A second heat treatment process is performed on the carburized graphitization catalyst in an inert or reductive gas atmosphere to thereby form graphene shells on surfaces of the carburized graphitization catalyst.
