1. A thermo-electrochemical reactive capture apparatus, the apparatus comprising:
an anode and a cathode, wherein the anode includes a first catalyst, wherein the cathode includes a second catalyst;
a porous ceramic support positioned between the anode and the cathode;
an electrolyte mixture in pores of the ceramic support, wherein the electrolyte mixture is configured to be molten at a temperature below about 600 degrees Celsius; and
a steam flow system on an outer side of the cathode, wherein the outer side of the cathode is opposite an inner side of the cathode, wherein the inner side of the cathode is adjacent to the ceramic support,
wherein the cathode is configured to generate syngas upon energization thereof and contact with carbon dioxide, wherein the syngas comprises carbon monoxide gas and hydrogen gas.
