The quality of graphene produced by electrochemical exfoliation of graphite in aqueous solution is inferior to the material produced by mechanical exfoliation, due to the functionalization of carbon by reactive oxygen radical species derived from water oxidation. Andinet Ejigu, Robert A. W. Dryfe, and co‐workers describe in article number 1804357 how Co2+ additives act as effective antioxidants, minimizing...
A new approach is presented, based on the unexpectedly versatile role of transition metal ions, to produce high‐quality graphene via an anodic electrochemical exfoliation route, and the capability of the resultant material in energy storage applications are illustrated. The method is based on graphene exfoliation in the presence of transition metals (Co2+ and Fe3+) which act as antioxidants, preventing...
