Enhancing CO2 Electroreduction to Ethanol on Copper–Silver Composites by Opening an Alternative Catalytic Pathway
Open accessAbstract
A fundamental question in the electrochemical CO 2 reduction reaction (CO 2 RR) is how to rationally control the catalytic selectivity. For instance, adding a CO-selective cocatalyst like Ag to Cu shifts the latter’s CO 2 RR selectivity toward C 2 products, but the underlying cause of the change is unclear. Herein, we show that, during CO 2 RR, the abundant CO availability at Cu−Ag boundaries facilitates C-C coupling on Cu to selectively generate ethanol through an otherwise closed pathway. Oxide-derived Cu nanowires mixed with 20 nm Ag particles (Cu:Ag mole ratio of 1:20) catalyzed CO 2 reduction to ethanol with a maximum current density of −4.1 mA/cm 2 and ethanol/ethylene Faradaic efficiency ratio of 1.1 at −1.1 V vs RHE. These figures of merit are, respectively, 5 and 3 times higher than those for pure oxide-derived Cu nanowires. CO 2 RR on CuAg composite catalysts with different Ag:Cu ratios and Ag particle sizes reveals that ethanol production scales with the amount of CO evolved from Ag sites and the abundance of Cu–Ag boundaries, and, very interestingly, without significant modifications to ethylene formation. Computational modeling shows selective ethanol generation via Langmuir–Hinshelwood *CO + *CH x ( x = 1, 2) coupling at Cu–Ag boundaries and that the formation of energy-intensive CO dimers is circumvented.

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.
