Abstract

Electrodeposition from plating baths containing 3,5-diamino-1,2,4-triazole (DAT) as an inhibitor gives Cu films exhibiting high surface area and high CO 2 reduction activities. By changes in the pH and deposition current density, the morphologies of the Cu films are varied to exhibit wire, dot, and amorphous structures. Among these Cu films, the CuDAT-wire samples exhibit the best CO 2 reduction activities activity with a Faradaic efficiency (FE) for C 2 H 4 product formation reaching 40% at −0.5 V vs RHE, a FE for C 2 H 5 OH formation reaching 20% at −0.5 V vs RHE, and a mass activity for CO 2 reduction at −0.7 V vs RHE of ∼700 A/g.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In gas phase systems, catalysts that have poor CO2RR selectivity in liquid phase electrolyzers (Pt, Fe, Fe-Co, Pt-Ru, etc.) can produce methanol, isopropanol, and >C5 long chain products, although in small quantities.

    “Researchers have also used catalysts that have poor CO2RR selectivity in liquid phase electrolyzers (Pt, Fe, Fe-Co, Pt-Ru, etc.) to produce products not typically observed in other flow cell systems, such as methanol, [146][147][148][149] isopropanol, [150,151] and >C5 long chain products, although in small quantities.[152,153]”

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.
