| description | The invention belongs to the technical field of graphene film preparation, and discloses a two-dimensional single-layer dendritic crystal graphene film and a preparation method thereof. According to the method, a chemical vapor deposition two-step growth method is adopted, that is, hydrogen continues to be introduced after a graphene continuous single-layer film is synthesized, and the high-quality large-area continuous single-layer graphene dendritic crystal film is obtained through the hydrogen etching effect. A Raman spectrogram proves that the graphene is a single layer, the 2D peak intensity of the graphene is greater than the G peak, and the graphene has a perfect single Lorentz peak pattern. The obtained two-dimensional single-layer dendritic crystal graphene film is good in stability and continuity, has excellent sensing performance and catalytic performance, and has important application prospects in the fields of sensing and photocatalysis.
