Abstract
In this work, we demonstrate that graphene oxide (GO) can be reversibly converted to reduced-graphene-oxide (rGO) through the use of electric current. Strong electric field could cause ionization of water molecules in air to generate ions at cathode, causing GO to be reduced. When the bias is reversed, the same electrode becomes positive and ions are produced. According to Le Chatelier Principle, it then favors the reverse reaction, converting rGO back to GO, . X-ray spectroscopy and Raman spectroscopy were carried to verify the conversion reversibility in the reversed process.
