"United States Patent Application 20120132538 - Electrochemical Production of Butanol from Carbon Dioxide and Water; 2012; Inventors: Emily Barton Cole, Andrew Bocarsly, et. al., NJ and DC; Abstract: Methods and systems for electrochemical production of butanol are disclosed. A method may include, but is not limited to, steps (A) to (D). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte, a catalyst, and a cathode. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient for the cathode to reduce the carbon dioxide to a product mixture. Step (D) may separate butanol from the product mixture".
