Producing graphene from carbon dioxide

The general public knows the chemical compound of carbon dioxide as a greenhouse gas in the atmosphere and because of its global-warming effect. However, carbon dioxide can also be a useful raw material for chemical reactions. A working group at Karlsruhe Institute of Technology (KIT) has now reported on this unusual application in the ChemSusChem journal. They are using carbon dioxide as a raw material to produce graphene, a technological material which is currently the subject of intense study.
