Electrochemical Synthesis of Methanol from CO 2 in High‐Pressure Electrolyte

Open access
Li, Jianwei, Prentice, Geoffrey·1997·Journal of The Electrochemical Society

Abstract

We synthesized from and on a copper cathode in the high‐pressure system. Methanol was the only product of reduction detected in the electrolytic solution, with a maximum current efficiency for methanol production of 40% at a current density of 9 mA/cm 2 and potential of −1.1 V vs. Ag/AgCl. This is the highest efficiency yet reported for methanol production at this current density. Current‐potential curves shifted in the positive potential direction with increasing temperature and with increasing pressure up to approximately 60 atm. When the applied potential is more negative than about −1.2 V vs. Ag/AgCl, the current density decreases dramatically with time. Electrolyte conductivity in this system increases with increasing temperature, increasing concentration of LiCl, and decreasing pressure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
