Abstract
Official abstract text for this publication.
A method and a device for electrochemical reduction of carbon dioxide for preparing a high-concentration formate salt. Carbon dioxide is continuously supplied to a cathode unit and is continuously supplied to a metal hydroxide to the anode unit. A voltage or current is applied to the cathode unit and the anode unit for reducing the carbon dioxide to obtain the formate salt.
First claim
Opening claim text (preview).
We claim: 1. A method for electrochemical reduction of carbon dioxide, comprising: in a reactor of electrochemical reduction of carbon dioxide including an anode unit and a cathode unit, continuously supplying carbon dioxide to the cathode unit and continuously supplying a metal hydroxide to the anode unit; and applying voltage and current to the cathode unit and the anode unit for reducing the carbon dioxide to obtain a formate salt, wherein the cathode unit includes both Hg and a metal formed on a surface of a foam substrate electrode, and wherein the metal includes a member selected from the group consisting of Ag, In, Sn, Pb, Cu, and combinations thereof, wherein the metal hydroxide is an alkali metal hydroxide including a member selected from the group consisting of KOH, NaOH, LiOH, and combinations thereof, wherein a current density depending on the voltage applied to the cathode unit and the anode unit is between 100 mA/cm 2 to 350 mA/cm 2 , and wherein the metal hydroxide is continuously supplied to the anode unit so that a concentration of the formate salt of 1.0 M or more is continuously obtained by reduction of the carbon dioxide.
