  • Publication number: 20120277465
    Abstract: Methods and systems for electrochemical conversion of carbon dioxide to carboxylic acids, glycols, and carboxylates 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 and a cathode. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient to reduce the carbon dioxide to a carboxylic acid intermediate.

  • Patent number: 5368701
    Abstract: Crystalline solids including Zintl anions have been synthesized by an electrolytic process that uses a cathode whose composition is an alloy including the elements forming the Zintl ion and an electrolyte that comprises a solvent that is basic and polar, such as ethylenediamine, and a supporting electrolyte, advantageously organic, that provides a suitable cation for the Zintl anion. Specific examples of solids that have been crystallized include tetraphenylphosphonium gold telluride, tetraphenylphosphonium gallium telluride, and tetrapropylammonium antimony telluride.
