Tuning the Microenvironment in Gas-Diffusion Electrodes Enables High-Rate CO2 Electrolysis to Formate
Abstract
Electroreduction of CO 2 to formate on Bi-based catalyst is a promising route for CO 2 recycling and sustainable fuel production. The use of gas-diffusion-electrode (GDE) flow cells has generally improved the rate of CO 2 electrolysis, while the local reaction environment in GDEs and its impact on the electrolysis remain to be understood. Here, we report that tuning the microenvironment of Bi-based catalyst in a GDE by adding hydrophobic polytetrafluoroethylene (PTFE) nanoparticles in the catalyst layer can substantially enhance CO 2 electrolysis, achieving a partial current density of 677 mA cm –2 for formate production and 35% single-pass CO 2 conversion at −0.7 V versus RHE under 9-sccm CO 2 gas flow. It is revealed that a moderate hydrophobicity of the catalyst layer can establish a microenvironment with a balance between gaseous CO 2 and liquid electrolyte inside the catalyst layer, which reduces the diffusion layer thickness to accelerate CO 2 mass transport and forms highly active reaction zones near solid–liquid–gas interfaces.

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.
