Description
Summary:We identify a method and its mechanism for producing nanostructured graphite via the electrochemical reduction of synthetic flue gas (a mixture of CO 2 and SO 2 ) in molten Li 2 CO 3 -Na 2 CO 3 -K 2 CO 3 -Li 2 SO 4 at a relatively low temperature (775 °C), the lowest temperature reported for artificial graphite preparation without a metal or metal compound catalyst. A low temperature graphitization process integrates SO 2 and CO 2 capture and reduction, promising a novel method to prepare graphite.
