A new green graphene made from eucalyptus trees eliminates the need for toxic chemical agents.
As useful as graphene sheets have become, their production on a large scale requires the use of chemical reduction agents, which are often toxic. As an alternative, the team from RMIT turned to eucalyptus bark extract as the reducing agent for synthesizing graphene. The new method was not only more affordable and non-toxic, but the resulting graphene also performed as well as traditional graphene.
The team now plan to determine precisely which compounds in the eucalyptus bark extract are responsible for the graphene reduction in order to improve the efficiency of the method.
