Reduction of Graphene Oxide Using an Environmentally Friendly Method and Its Application to Energy-Related Materials

Abstract

Since graphene oxide can be synthesized in large quantities by oxidation of inexpensively available natural graphite and can be dispersed in water, it can be coated onto a variety of substrates by solution processes. Graphene oxide can also be reduced to yield reduced graphene oxide, which has similar electronic features to graphene. This review introduces the environmentally friendly methods for the synthesis of reduced graphene oxide utilizing electrochemical and thermal methods and summarizes our recent research results on their application to energy-related materials such as electric double-layer capacitors, thermoelectric devices, transparent conductive films, and lithium-ion secondary batteries.
