Oxygen Vacancy Tuning toward Efficient Electrocatalytic CO2 Reduction to C2H4
Abstract
Electrochemical reduction of carbon dioxide (CO 2) is a promising approach to solve both renewable energy storage and carbon‐neutral energy cycles, while the capability of selective reduction to C 2+ products has still been quite limited. In this work, partially reduced copper oxide nanodendrites with rich surface oxygen vacancies (CuOx–Vo) are developed, serving as excellent Lewis base sites for enhanced CO 2 adsorption and subsequent electrochemical reduction. Theoretical calculations reveal that these oxygen vacancy‐rich CuOx surfaces provide strong binding affinities to the intermediates of *CO and *COH, but weak affinity to *CH 2, thus leading to efficient formation of C 2 H 4. As a result, the partially reduced CuOx nanodendrites exhibit one of the highest C 2 H 4 production Faradaic efficiencies of 63%. The electrochemical stability test further shows that the C 2 H 4 Faradaic efficiency strongly depends on the oxygen vacancy density in CuOx, which can further be regenerated for several cycles, thus suggesting the critical role of oxygen vacancies for the C 2 product selectivity.

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.
