Sulfur-Modified Copper Catalysts for the Electrochemical Reduction of Carbon Dioxide to Formate
Open accessAbstract
Abstract The electrocatalytic CO2 reduction reaction (eCO2RR) has been gaining increasing attention owing to its potential to contribute to sustainability in our society, although enhanced catalytic performance is a prerequisite for its implementation. Herein, Cu electrocatalysts modified with sulfur proved to selectively produce formate via aqueous eCO2RR and thus to unexpectedly prevent the mechanistic fingerprint of Cu (i.e., the CO path). Initially, sulfur-modified copper catalysts (Cu–S) were prepared by the in situ reductive reconstruction of nano CuS precursors, revealing a positive correlation between particle size and selectivity toward formate. Subsequent studies over targeted submicron Cu–S particles with varying sulfur content demonstrated their evolution under reaction conditions, attaining a similar surface state comprising metallic Cu and sulfide phases, irrespective of the initial structure of the materials. In accordance, the initial sulfur content showed only a very limited influence on the catalytic performance, which remained at approximately 80% Faradaic efficiency toward formate at −0.8 V vs RHE, outperforming all cost-effective, earth-abundant, and nontoxic electrocatalysts reported to date for the production of formate via the aqueous eCO2RR.

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.
