Researchers from Nanyang Technological University in Singapore demonstrated how Indium and Indium chloride (InCl) can improve the process of reducing graphene oxide to graphene. The Indium helps by regenerating the sp2-conjugated system or selectively removing key oxygen-containing groups that could potentially decrease the performance of the graphene.

The researchers developed a method to apply the Indium, and they say that this method can be applied independently or in conjunction with other reducing agents to further improve the quality of chemically reduced graphene.
