Abstract: The invention belongs to the technical field of inorganic compounds, and particularly, relates to a method for directly preparing graphene by taking CBr4 as a source material and using methods such as molecular-beam epitaxy (MBE) or chemical vapor deposition (CVD). A method for preparing graphene comprises the following steps: selecting a proper material as a substrate; directly depositing a catalyst and CBr4 on a surface of the substrate; and performing annealing treatment on the sample obtained through deposition. Compared with other technologies, an innovative point of the method in the invention is that the catalyst and CBr4 source can be quantitatively and controllably deposited on any substrate, and the catalyst and CBr4 source react on the surface of the substrate to form the graphene, so that the dependence of the graphene growth on a substrate material can be reduced to a great extent, and different substrate materials can be selected according to different application backgrounds.

Abstract translation: 本发明属于无机化合物的技术领域，特别涉及通过以CBr4作为源材料并使用分子束外延（MBE）或化学气相沉积（CVD）等方法直接制备石墨烯的方法。 制备石墨烯的方法包括以下步骤：选择合适的材料作为基材; 将催化剂和CBr 4直接沉积在基材的表面上; 对通过沉积获得的样品进行退火处理。 与其他技术相比，本发明方法的创新点是催化剂和CBr4源可以定量和可控地沉积在任何基材上，催化剂和CBr4源在基材表面上反应形成石墨烯，因此 石墨烯生长对衬底材料的依赖性可以在很大程度上降低，并且可以根据不同的应用背景来选择不同的衬底材料。
