： Graphene is a new type of two-dimensional carbon nanomaterial composed of single-layer carbon atoms and has received great attentions because of its excellent physical and chemical properties. Three-dimensionally structured graphene is obtained by curving and assembling the two-dimensional sheet-like graphene materials. This structure can effectively tune the electrical, optical, chemical, mechanical and catalytic properties of graphene. The devices constructed based on the three-dimensional graphene exhibit more excellent performances in applications of energy-storage, sensor, catalysis, etc. Therefore, the fabrication and the use of three-dimensional graphene materials have been the research hot spot at present. This paper introduced the types of three-dimensional graphene and its composites, and reviewed the challenges and the development prospects of these materials in applications
