Elucidation of formation mechanism of graphene oxide – Successful observation of the state during reaction in real time

March 03(Fri), 2017

A research group led by Yuta Nishina, Associate Professor at Research Core for Interdisciplinary Sciences, Okayama University has successfully monitored in real time the process of graphene oxide being synthesized from graphite, a reaction that graphite is oxidized and then peels off.  This is the world’s first demonstration of the mechanism of graphene oxide formation.  The study was reported in the U.S.’s scientific journal Chemistry of Materials as an up-to-the-minute online article on March 2.

Graphene oxide is a substance in a form of flakes of about 1 nm (nanometer) thick.  In recent years, many applications have been studied, such as electrode materials, catalysts, lubricants, resin reinforcing materials, and thermally conductive materials, and there have been reports suggesting excellent performance of graphene oxide.  With the synthesis process not fully understood, however, synthesis of graphene oxide has been carried out by many different recipes by different research groups, resulting in poor reproducibility.

By revealing the mechanism of graphene oxide formation, this finding has unveiled factors responsible for changes in physical properties of graphene oxide.  This finding has also enabled safe synthesis of graphene oxide, promising for large-amount synthesis for practical use.  The group is looking to introduce graphene oxide into the society and preparing for commercialization and other forms.
