Reduction of Carbon Dioxide to Formate at Low Overpotential Using a Superbase Ionic Liquid
A new low‐energy pathway is reported for the electrochemical reduction of CO2 to formate and syngas at low overpotentials, utilizing a reactive ionic liquid as the solvent. The superbasic tetraalkyl phosphonium ionic liquid [P66614][124Triz] is able to chemisorb CO2 through equimolar binding of CO2...

| description | A new low‐energy pathway is reported for the electrochemical reduction of CO2 to formate and syngas at low overpotentials, utilizing a reactive ionic liquid as the solvent. The superbasic tetraalkyl phosphonium ionic liquid [P66614][124Triz] is able to chemisorb CO2 through equimolar binding of CO2 with the 1,2,4‐triazole anion. This chemisorbed CO2 can be reduced at silver electrodes at overpotentials as low as 0.17 V, forming formate. In contrast, physically absorbed CO2 within the same ionic liquid or in ionic liquids where chemisorption is impossible (such as [P66614][NTf2]) undergoes reduction at significantly increased overpotentials, producing only CO as the product.
[P66614][124Triz], eine bei Raumtemperatur flüssige ionische Verbindung (RTIL), öffnet einen alternativen energetisch günstigen Pfad für die Umwandlung von CO2 in Formiat. Hier senkt die chemische Bindung von CO2 an das RTIL‐Anion, durch die CO2 nicht mehr linear, sondern gebogen vorliegt, erstmals die Aktivierungsenergie für die elektrochemische CO2‐Reduktion. |
