Abstract
|
|
|
|
The electrochemical carbon dioxide reduction to produce acetaldehyde, methanol and ethanol is investigated by using perovskite type electrode (). The experiments were Performed under 100 mA/cm2 and -2 to -2.5 V vs. Ag/AgCl. The highest faradaic efficiencies for methanol, ethanol, acetaldehyde were 11.6, 15.3, and 6.2%, respectively. The experimental data demonstrated that the capability of the perovskite type oxide for the electrode of electrochemical carbon dioxide reduction to produce alcohols was superior to other metal electrode. Key words : Perovskite, Electrode, Alcohol Formation, Electrochemical Reduction, Carbon Dioxide Fixation.
