藉由电化学剥落制备二维碳材料;PREPARATION OF TWO DIMENSIONAL CARBON MATERIALS BY ELECTROCHEMICAL EXFOLIATION

摘要

本发明系关于一种藉由电化学剥落制备石墨烯之方法，其包含：- 提供第一电极E1及第二电极E2，其中至少该第一电极E1包含具有分层结构之碳起始材料；- 使至少该第一电极E1与液体电解质接触，其中该液体电解质包含- 铵阳离子，以及- 无机含硫阴离子，- 在该第一电极E1与该第二电极E2之间施加电位，以便自该碳起始材料剥落石墨烯。; - bringing at least the first electrode E1 in contact with a liquid electrolyte, wherein the liquid electrolyte comprises - an ammonium cation, and - an inorganic sulphur-containing anion, + applying an electric potential between the first electrode E1 and the second electrode E2 so as to exfoliate graphene from the carbon starting material.
