Abstract

The embodiments herein relate to methods and apparatus for forming graphitic material from a carbon oxide feedstock in an electroplating chamber containing molten inorganic carbonate as electrolyte. Carbon dioxide flows into a reaction chamber containing one or more cathodes, one or more anodes, and a molten carbonate electrolyte. The carbon dioxide and/or carbonate reduces at the cathode to form graphitic material, which may be removed from the surface of the cathode through various mechanisms. The graphitic material is then separated out from the electrolyte.
