Selective removal of hydroxyl groups on graphene oxide has been achieved with ethanethiol–aluminium chloride complexes. The reduced graphene material exhibits improved electrochemical properties over its precursor graphite oxide (layered structure of graphite oxide depicted by the red layered wall of Antelope Canyon in Arizona). The selective defunctionalization of oxygen groups on graphene oxide opens up new opportunities for specific tailoring of graphene materials. For more information see the Full Paper by M. Pumera and C. K. Chua on page 2005 ff.
