Abstract

The conversion of CO 2 to CO is demonstrated in an electrolyzer flow cell containing a bipolar membrane at current densities of 200 mA/cm 2 with a Faradaic efficiency of 50%. Electrolysis was carried out by delivering gaseous CO 2 at the cathode with a silver catalyst integrated in a carbon-based gas diffusion layer. Nonprecious nickel foam in a strongly alkaline electrolyte (1 M NaOH) was used to mediate the anode reaction. While a configuration where the anode and cathode were separated by only a bipolar membrane was found to be unfavorable for robust CO 2 reduction, a modified configuration with a solid-supported aqueous layer inserted between the silver-based catalyst layer and the bipolar membrane enhanced the cathode selectivity for CO 2 reduction to CO. We report higher current densities (200 mA/cm 2 ) than previously reported for gas-phase CO 2 to CO electrolysis and demonstrate the dependence of long-term stability on adequate hydration of the CO 2 inlet stream.

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.
