▎ 摘　　要

NOVELTY - The device has an expanded graphite worm cake (4) that is embedded at a bottom portion of a container (1) filled with a weak acid electrolyte (5). The inner surface of a platinum wire fixing plate (2) is vertically welded with multiple platinum wires (3). A conductive metal mesh (8) is horizontally placed in a weak acid electrolyte. The expanded graphite worm cake and the platinum wire fixing plate are connected with positive electrode of power supply (6). The conductive metal mesh is connected with the negative electrode of the power supply. USE - Device for preparing graphene by using platinum wire and graphite cake. ADVANTAGE - The expanded graphite is stripped out of the electrolyte by layer by layer electrolysis of expanded graphite worm cakes by conductive metal mesh. The expanded graphite worm is fully stripped after the continuous electrolysis of platinum wire. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene by using platinum wire and graphite cake. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene by using platinum wire and graphite cake.
