Abstract:
1. A method for fabricating a three dimensional graphene structure, comprising: growing graphene from all dimensions of a metal catalyst template in a tube, a rod, a sphere, a cube, a coil, or a cuboid; and removing the template by dissolving the template on which graphene has grown, in an etching solvent, wherein a shape of the three dimensional graphene structure corresponds to the shape of the metal catalyst template and the three dimensional graphene structure includes a carbon nanotube, a graphene rod, a fullerene, a graphene cube, a graphene coil, or a graphene cuboid, and a length of each of the three dimensional graphene structure and the metal catalyst template is from a few nanometers to a few millimeters.
