Abstract
Official abstract text for this publication.
The present disclosure provides a system for electrochemical conversion of carbon dioxide, including: a reduction electrode unit to which carbon dioxide is supplied and including a metal-containing electrode; an oxidation electrode unit including a sacrificial electrode; and an electrolyte unit including an aprotic polar organic solvent and an auxiliary electrolyte, which is in contact with the reduction electrode unit and the oxidation electrode unit, and the carbon dioxide supplied to the reduction electrode unit is electrochemically reduced so as to produce an oxalate salt.
First claim
Opening claim text (preview).
We claim: 1 . A system for electrochemical conversion of carbon dioxide, comprising: a reduction electrode unit to which carbon dioxide is supplied and including a metal-containing electrode; an oxidation electrode unit including a sacrificial electrode; and an electrolyte unit including an aprotic polar organic solvent and an auxiliary electrolyte, which is in contact with the reduction electrode unit and the oxidation electrode unit, wherein the carbon dioxide supplied to the reduction electrode unit is electrochemically reduced so as to produce an oxalate salt. 2 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein the metal-containing electrode includes a member selected from the group consisting of Hg, Ag, Sn, Cu, Zn, Sb, alloys thereof, amalgam, and combinations thereof. 3 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein the sacrificial electrode is selected from the group consisting of Zn, Mg, Li, Na, Al, and combinations thereof. 4 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein the aprotic polar organic solvent includes a member selected from the group consisting of dimethyl sulfoxide, dimethyl formamide, and combinations thereof. 5 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein the auxiliary electrolyte includes a member selected from the group consisting of tetrabutylammonium hexafluorophosphate (TBA.PF 6 ), tetrabutylammonium perchlorate (TBAP), tetrabutylammonium tetrafluoroborate (TBA.BF 4 ), and combinations thereof. 6 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein the oxalate salt is represented by the following Chemical Formula 1, M x C 2 O 4 ; [Chemical Formula 1] wherein in the above Formula, M is Zn, Mg, Li, Na, or Al, and x is 1 or 2. 7 . The system for electrochemical conversion of carbon dioxide of claim 1 , wherein a purity of the oxalate salt is 90% or more.
