In this study, a simple and versatile concept is presented based on a honeycomb polymer membrane\u2010electrode assembly (HMEA). By covering copper foil electrodes with a PMMA\u2010\n                    <jats:italic>b<\/jats:italic>\n                    \u2010P4VP porous pH\u2010sensitive polymer membrane, the electrode selectivity in the CO\n                    <jats:sub>2<\/jats:sub>\n                    RR shifts to C\n                    <jats:sub>2<\/jats:sub>\n                    molecules. It is reported that both the bio\u2010inspired honeycomb structure of the polymer and its pH\u2010sensitivity lead to a Cassie\u2010Baxter behavior in KHCO\n                    <jats:sub>3<\/jats:sub>\n                    aqueous electrolyte, which limits the hydrogen evolution reaction and concentrates the CO\n                    <jats:sub>2<\/jats:sub>\n                    and intermediates in the vicinity of the electrode surface. A systematic and drastic shift in selectivity is observed when using the porous polymer, toward formate at potentials below 0.9\n                    <jats:italic>V<\/jats:italic>\n                    <jats:sub>RHE<\/jats:sub>\n                    , and toward ethanol and ethylene for potentials above this value. After 24\u2009h of electrocatalysis, the selectivity and efficiency of the HMEA can be restored by simple drying at room temperature. The versatility of the HMEA concept is also extended to silver foil electrodes, showing the decrease of hydrogen production and the shift of the electrode selectivity in the CO\n                    <jats:sub>2<\/jats:sub>\n                    RR toward carbon monoxide, formate, and ethanol.\n                  <\/jats:p>","DOI":"10.1002\/cssc.202501620","type":"journal-article","created":{"date-parts":[[2025,9,18]],"date-time":"2025-09-18T12:27:57Z","timestamp":1758198477000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["pH\u2010Sensitive and Self\u2010Regenerative Honeycomb Polymer Membrane\u2010Electrode Assembly for CO\n                    <sub>2<\/sub>\n                    Reduction: Shifting Selectivity toward C\n                    <sub>2<\/sub>\n                    Molecules"],"prefix":"10.1002","volume":"18","author":[{"given":"Sandra","family":"Castani\u00e9","sequence":"first","affiliation":[{"name":"E2S UPPA Bio\u2010inspired Materials Group: Functionalities &amp; Self\u2010Assembly  Pau 64000 France"},{"name":"E2S UPPA CNRS IPREM UMR 5254 Institut des sciences analytiques et de physico\u2010chimie pour l'environnement et les mat\u00e9riaux Technop\u00f4le Helioparc Universite de Pau et des Pays de l\u2019Adour  2 Av. du Pr\u00e9sident Pierre Angot Pau Cedex 9 64053 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00e9onard","family":"Curet","sequence":"additional","affiliation":[{"name":"E2S UPPA Bio\u2010inspired Materials Group: Functionalities &amp; Self\u2010Assembly  Pau 64000 France"},{"name":"E2S UPPA CNRS IPREM UMR 5254 Institut des sciences analytiques et de physico\u2010chimie pour l'environnement et les mat\u00e9riaux Technop\u00f4le Helioparc Universite de Pau et des Pays de l\u2019Adour  2 Av. du Pr\u00e9sident Pierre Angot Pau Cedex 9 64053 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emilio","family":"Palomares","sequence":"additional","affiliation":[{"name":"Institute of Chemical Research of Catalonia (ICIQ)  Avda.
