摘要：
We identify a method and its mechanism for producing nano-structured graphite via the electrochemical reduction of synthetic flue gas (a mixture of CO2 and SO2) in molten Li2CO3- Na2CO3- K2CO3-Li2SO4 at a relatively low temperature (775 degrees C), the lowest temperature reported for artificial graphite preparation without a metal or metal compound catalyst.
