Abstract

High deuteration yields are difficult to attain with conventional chemical synthesis methods. In this work, we demonstrate that deuterated chemicals can be produced using electrochemical CO₂ reduction in the presence of D₂O. The absence of H₂O enables deuteration yields over 99% for products such as ethanol-d₆ and formate-d. With a D₂O solvent, the competing D₂ evolution reaction is completely suppressed at low current densities while being kept <10% at a higher 300 mA/cm².
