Cu2O-loaded gas diffusion electrodes for the continuous electrochemical reduction of CO2 to methanol
Open accessAbstract
Abstract Gas-diffusion electrodes are prepared with commercial Cu2O and Cu2O–ZnO mixtures deposited onto carbon papers and evaluated for the continuous CO2 gas phase electroreduction in a filter-press electrochemical cell. The process mainly produced methanol, as well as small quantities of ethanol and n-propanol. The analysis includes the evaluation of key variables with effect in the electroreduction process: current density (j = 10–40 mA cm−2), electrolyte flow/area ratio (Qe/A = 1–3 ml min−1 cm−2) and CO2 gas flow/area ratio (Qg/A = 10–40 ml min−1 cm−2), using a 0.5 M KHCO3 aqueous solution. The maximum CO2 conversion efficiency to liquid-phase products was 54.8% and 31.4% for Cu2O and Cu2O/ZnO-based electrodes at an applied potential of −1.39 and −1.16 V vs. Ag/AgCl, respectively. Besides, the Cu2O/ZnO electrodes are expected to catalyze the CO2 electroreduction for over 20 h. These results may provide new insights into the application of gas diffusion electrodes to alleviate mass transfer limitations in electrochemical systems for the transformation of CO2 to alcohols.

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.
