▎ 摘　　要

NOVELTY - Electrochemical conversion of carbon dioxide to graphene comprises: (i) passing carbon dioxide gas into electrolysis device, electrochemical dissociation reaction occurs in the device and carbon nanosheets are generated on the cathode of the device, and wrapping the carbon nanosheets on the cathode; (ii) inserting wrapped the nanosheets as cathode, the stripping anode into the electrolyte of the stripping electrolysis device and at the same time inserting into the stripping cathode and the stripping power is turned on, in the stripping electrolysis device, the ions in the electrolyte enter the nanosheet under the action of the electric field and the internal water electrolysis generates gas and electrochemically strips carbon nanosheets to obtain graphene suspension; (iii) centrifugal separation of the suspension and washing to remove soluble impurities to form solid product; and (iv) freeze-drying to remove moisture to form graphene. USE - The method is useful for electrochemical conversion of carbon dioxide to graphene. ADVANTAGE - The method provides graphene with high efficiency, environmental protection and low cost.
