TWO-DIMENSIONAL CARBON MATERIALS PREPARED BY ELECTROCHEMICAL EXFOLIATION

摘要

The present invention relates to a process for preparing graphene by electrochemical exfoliation, which comprises: - providing a first electrode E1 and a second electrode E2, wherein at least the first electrode E1 comprises a carbon starting material having a layered structure; - bringing at least the first electrode E1 in contact with a liquid electrolyte, wherein the liquid electrolyte comprises a sulfonic acid or a salt thereof, and/or a sulphuric acid monoester or a salt thereof; - applying an electric potential between the first electrode E1 and the second electrode E2 so as to exfoliate graphene from the carbon starting material.
