Graphene has perfect two-dimensional structure and a number of excellent optical, mechanical, thermal, electrical, and chemical performances. Therefore, graphene attracts much attention since it was discovered. Many methods have been employed to prepare graphene in the last ten years, are discharge method has attracted much attentions because of its high efficiency, safety, reliability, preparation of high-quality graphene, environmental friendliness, easy to obtain doped graphene and so on. This paper summarizes the effect factors for graphene preparation by arc discharge method, such as atmosphere, pressure, catalyst, and magnetic field. The growth mechanisms of graphene preparation related to above factors are discussed. The problems of graphene preparation by arc discharge method are analyzed, and corresponding solutions are provided. Finally, the current status of graphene research in China is analyzed, the development trend of graphene preparation by arc discharge method is forecasted.
