Self-Cleaning CO2 Reduction Systems: Unsteady Electrochemical Forcing Enables Stability
Open accessAbstract
The electrochemical conversion of CO 2 produces valuable chemicals and fuels. However, operating at high reaction rates produces locally alkaline conditions that convert reactant CO 2 into cell-damaging carbonate salts. These salts precipitate in the porous cathode structure, block CO 2 transport, reduce reaction efficiency, and render CO 2 electrolysis inherently unstable. We propose a self-cleaning CO 2 reduction strategy with short, periodic reductions in applied voltage, which avoids saturation and prevents carbonate salt formation. We demonstrate this approach in a membrane electrode assembly (MEA) with silver and copper catalysts, on carbon and polytetrafluoroethylene (PTFE)-based gas diffusion electrodes, respectively. When operated continuously, the C 2 selectivity of the copper–PTFE system started to decline rapidly after only ∼10 h. With the self-cleaning strategy, the same electrode operated for 157 h (236 h total duration), maintaining 80% C 2 product selectivity and 138 mA cm –2 of C 2 partial current density, at a cost of <1% additional energy input.

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.
