Product Selectivity Affected by Cationic Species in Electrochemical Reduction of CO2 and CO at a Cu Electrode
Abstract
Electroreduction of CO2 and CO was studied with a copper electrode in hydrogencarbonate solutions of various cations. Product selectivity was greatly affected by cationic species as well as HCO3− concentration. H2 evolution prevailed over CO2 reduction in Li+ electrolyte, whereas CO2 reduction was favorable in Na+, K+, and Cs+ solutions. C2H4 formation became greater than CH4 with increase of the cation size, i.e. with sequence of Li+, Na+, K+, Cs+. The variation of the product selectivity caused by cationic species is rationalized by the difference of outer Helmholtz plane (OHP) potential. The OHP potential will vary with cationic species in accordance with the degree of specific adsorption. The concentration of H+ at the electrode will depend upon the OHP potential, since H+ is a charged species. This difference of pH at the electrode will lead to the variation of product selectivity.

“Ohmic losses may be prohibitively large in the case of less conductive electrolytes, such as 0.1 M KHCO3 (conductivity of 10 mS/cm as compared to 1.0 M KOH which has a conductivity of 220 mS/cm), [218,219] where the energy efficiency would be greatly impacted”

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.
