Synthesis of nanostructured graphite via molten salt reduction of CO2 and SO2 at a relatively low temperature

Abstract

We identify a method and its mechanism for producing nanostructured 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 °C), the lowest temperature reported for artificial graphite preparation without a metal or metal compound catalyst.
