The present invention relates to a method for preparing doped graphene using microwaves. According to the present invention, graphite and an organic compound for doping are reacted in the presence of microwave to intercalate graphite, and the organic compound for doping is inserted between the graphite layer and the layer of the multi-layer structure, Graphene grains doped with 0.01 to 10% by weight of heterogeneous elements can be obtained by removing the graphene layer. This is because the use of toxic chemicals such as hydrazine is suppressed in comparison with the graphene of the conventional chemical stripping method, so that graphene having much higher purity can be easily and environmentally friendly, and at the same time, compared with the graphene- Which is very inexpensive and simple process to suppress the utilization of complicated high-priced equipment such as doped graphene, which can be usefully used in the production of graphene semiconductors. |
