Abstract
A method for purification of carbon dioxide from a mixture of gases is disclosed. The method generally includes steps (A) and (B). Step (A) may bubble the gases into a solution of an electrolyte and a catalyst in an electrochemical cell. The electrochemical cell may include an anode in a first cell compartment and a cathode in a second cell compartment. The cathode generally reduces the carbon dioxide into one or more compounds. The anode may oxidize at least one of the compounds into the carbon dioxide. Step (B) may separate the carbon dioxide from the solution.
