▎ 摘　　要

NOVELTY - Device comprises a container (1), platinum (2), metal plate (4), weak acid electrolyte (5), a power supply (6), expanded graphite worm and many platinum wire. The metal plate is embedded in the bottom of the container. The container is filled with electrolyte and mixed liquid of expanded graphite worm. The platinum wire fixing plate in vertical surface welded with many platinum wires. The anode of the power supply is connected with platinum wire fixing plate through a lead. The cathode of the power supply is connected through lead and the metal plate. USE - The device is useful for preparing graphene using platinum wire. ADVANTAGE - The processing method is simple and feasible. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene, comprising, taking the metal board is embedded at the bottom of the reaction container and the weak electrolyte filled with reaction vessel, adding expanded graphite worm after the platinum wire fixing plate is connected above the reaction vessel, the anode of the power supply is connected with platinum wire fixing plate through lead, negative pole of the power supply is connected through lead and the metal plate, turning on the power switching the expanded graphite worm to electrolyze, fully electrolyzing, washing the mixture of graphene and electrolyte and filtering, filtering to obtain the graphene for ultrasonic crushing and drying to obtain the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device for preparing graphene using platinum wire. Container (1) Platinum (2) Metal plate (4) Weak acid electrolyte (5) Power supply (6)
