Boosting CO2 Electroreduction to CH4 via Tuning Neighboring Single-Copper Sites
Abstract
We report single-atom Cu catalysts dispersed on nitrogen-doped carbon by a nitrogen-coordination strategy. The presence of nitrogen enabled good dispersion and attachment of atomic Cu species on the nitrogen-doped carbon frameworks with Cu–N x configurations. The Cu doping concentrations and Cu–N x configurations were well-tuned by the pyrolysis temperature. At a high Cu concentration of 4.9% mol, the distance between neighboring Cu–N x species was close enough to enable C–C coupling and produce C 2 H 4 . In contrast, at Cu concentrations lower than 2.4% mol, the distance between Cu–N x species was large so that the electrocatalyst favored the formation of CH 4 as C 1 products. Density functional theory calculations further confirmed the capability of producing C 2 H 4 by two CO intermediates binding on two adjacent Cu–N 2 sites, while the isolated Cu–N 4, the neighboring Cu–N 4, and the isolated Cu–N 2 sites led to formation of CH 4 . Our work demonstrates a facile approach of tuning active Cu sites for CO 2 electroreduction to different hydrocarbons.

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.
