Abstract: The excessive amount of carbon dioxide in the atmosphere is a global problem, and thus, the mitigation of carbon dioxide emissions should be an urgent issue. Technically, CO2 can be converted into valuable solid carbon through electrolysis in a molten salt electrolyte. Although studies have been conducted on the conversion of CO2 into various morphologies of solid carbon, the molten salt itself has received less attention in the research literature.
