Abstract

Copper-based materials are promising electrocatalysts for CO 2 reduction. Prior studies show that the mixture of copper (I) and copper (0) at the catalyst surface enhances multi-carbon products from CO 2 reduction; however, the stable presence of copper (I) remains the subject of debate. Here we report a copper on copper (I) composite that stabilizes copper (I) during CO 2 reduction through the use of copper nitride as an underlying copper (I) species. We synthesize a copper-on-nitride catalyst that exhibits a Faradaic efficiency of 64 ± 2% for C 2+ products. We achieve a 40-fold enhancement in the ratio of C 2+ to the competing CH 4 compared to the case of pure copper. We further show that the copper-on-nitride catalyst performs stable CO 2 reduction over 30 h. Mechanistic studies suggest that the use of copper nitride contributes to reducing the CO dimerization energy barrier—a rate-limiting step in CO 2 reduction to multi-carbon products.

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

  • By altering the reaction environment through increased electric fields, increased CO coverage, and/or increased catalyst strain, it is possible to improve the catalytic activity towards multi-carbon products.

    “Thus, by altering the reaction environment through increased electric fields (e.g.larger cations in the electrolyte), increased CO coverage (e.g. higher CO2 pressure), and/or increased catalyst strain (e.g.engineering a core-shell structure [63] ) it is possible to improve the catalytic activity towards multi-carbon products.”

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.
