International. Scientists reveal an ecological and economical strategy for the synthesis of soluble graphene (E-graphene) by using a solution of eucalyptus polyphenol that is obtained from a bark extract of the tree of the same name, as a replacement for the graphene oxide (GO) chemical reduction method.
The study reveals that the stable and homogeneous dispersion of E-graphene in various solvents, both aqueous and non-aqueous, confirms the powerful interactions between eucalyptus polyphenol compounds and graphene, evaluating the results of electrochemical performance by cyclic voltametry (CV) and galvanostatic charge/discharge (GCD).
These features demonstrate that this ecological approach has an excellent prospect, not only in the manufacture of high-performance supercapacitors, but also in the synthesis of graphene-based materials.
It should be noted that the chemical reduction method of GO usually includes reducing agents that are dangerous to both humans and the environment, so the sustainable synthesis of high-quality graphene sheets is one of the key issues recently in science and engineering.
