Electroreduction of carbon dioxide to carbon monoxide in molten LiCl + KCl, LiF + KF + NaF, Li2CO3 + Na2CO3 + K2CO3 and AlCl3 + NaCl

Electrochemical Production of Sustainable Hydrocarbon Fuels from CO2 Co-electrolysis in Eutectic Molten Melts

“…Generally, the presence of moisture with CO 2 gas in molten salt experiments is the basis for generating H 2 and CH 4 during electrolysis in most cases and provides feasibility to the reactions. , …”

“…The attractive characteristic in the case of molten chloride is the probability of producing CO or C directly from CO 2 reduction in the presence or absence of a carbonate ion . Carbonate ions (if added externally) are used as an important additive to molten chlorides to provide the oxide ions required for performing CO 2 reduction. , For absorbing more CO 2 gas into the molten salt, leading to an increase in product yield from electrolysis, the addition of oxides or carbonate salts into the molten chloride is considered preferable.…”

Conversion of CO[sub 2] to CO by Electrolysis of Molten Lithium Carbonate

“…High temperature electrochemical reduction of CO 2 includes two very different approaches: solid oxide gas electrolysis cells [7][8][9][10] and molten carbonate electrolysis cells. [11][12][13] The advantage of the carbonate electrolysis cells is that the CO 2 starting material and the CO and O 2 products do not mix. However, electrolysis in molten carbonates requires finding solutions to serious material stability problems.…”
