Microfluidic Reactor for the Electrochemical Reduction of Carbon Dioxide: The Effect of pH

Whipple, Devin T., Finke, Eryn C., Kenis, Paul J. A.·2010·Electrochemical and Solid-State Letters

Abstract

This article reports the development and characterization of a microfluidic reactor for the electrochemical reduction of carbon dioxide. The use of gas diffusion electrodes enables better control of the three-phase interface where the reactions take place. Furthermore, the versatility of the microfluidic reactor enables rapid evaluation of catalysts under different operating conditions. Several catalysts as well as the effects of electrolyte pH on reactor efficiency for reduction of to formic acid were tested. Operating at acidic pH resulted in a significant increase in performance: faradaic and energetic efficiencies of 89 and 45%, respectively, and current density of .

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Varela et al. demonstrated that while both Cl- and Br- can be used to suppress HER and improve the selectivity towards CO, I- can enhance hydrocarbon formation by donating more electronic charge to the Cu surface and facilitating charge transfer.

    “Studying the effects of different halides, Varela et al. demonstrated that while both Cl -and Br -can be used to suppress HER and improve the selectivity towards CO, I - can enhance hydrocarbon formation by donating more electronic charge to the Cu surface and facilitating charge transfer.[217]”

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.
