Abstract

一種石墨氧化物及/或石墨烯之製備方法，包含提供一電漿電解裝置，其中電漿電解裝置具有一電解液，以及電漿電解裝置之一陰極為一石墨電極；以及提供一陰極電流於石墨電極，使石墨電極進行一電漿電解反應以得到石墨氧化物及/或石墨烯。本發明藉由電漿電解程序，可在相對低溫、一般壓力及非常短的時間內，且不需濃縮酸及強氧化劑的條件下，即可製備石墨氧化物及/或石墨烯。本發明利用電漿電解程序將石墨直接製備為石墨氧化物及/或石墨烯，而不需任何事先純化。本發明之電漿電解程序相當具潛力，具有低成本、易製備、高效率及環保之優勢。 A graphite oxide and/or graphene preparation method includes providing a plasma electrolytic apparatus, where an electrolyte solution is provided and a graphite electrode is configured as a cathode of the plasma electrolytic apparatus; and providing a cathodic current so as to initiate a plasma electrolytic process at the graphite electrode to obtain graphite oxide and/or graphene. The graphite oxide and/or graphene can be synthesized through plasma electrolytic processing at relatively low temperature under atmospheric pressure within a very short period of time, without the need for concentrated acids or strong oxidizing agents. The present invention may prepare graphite oxide and/or graphene with plasma electrolytic process directly from graphite, without requiring any prior purification. This plasma electrolytic process of the present invention is quite promising and provided with advantages such as low cost, simple setup, high efficiency, and environmental friendliness.
