Notable features of such systems include the ability of Cu to generate C\n                    <jats:sub>2+<\/jats:sub>\n                    \u00a0products and the well\u2010defined active sites that allow for targeted structural tuning. However, the frequently observed in situ formation of Cu nanoclusters has undermined the advantages of the molecular frameworks. It is therefore desirable to develop Cu\u2010based catalysts that retain their molecular structures during electrolysis. In this context, a heterogenized binuclear hydroxo\u2010bridged phenanthroline Cu(II) compound with a short Cu\u00b7\u00b7\u00b7Cu distance is reported as a simple yet efficient catalyst for electrogeneration of ethylene and other C\n                    <jats:sub>2<\/jats:sub>\n                    products.

Furthermore, it exhibits high stability, manifested by no observable degradation during 15 h of continuous electrolysis. The preservation of the atomic distribution of the active sites throughout electrolysis is substantiated through comprehensive characterizations, including X\u2010ray photoelectron and absorption spectroscopy, scanning and transmission electron microscopy, UV\u2013vis spectroscopy, as well as control experiments. These findings establish a solid foundation for further investigations into targeted structural tuning, opening new avenues for enhancing the catalytic performance of Cu\u2010based molecular electrocatalysts.\n                  <\/jats:p>","DOI":"10.1002\/adma.202309526","type":"journal-article","created":{"date-parts":[[2023,11,21]],"date-time":"2023-11-21T05:43:06Z","timestamp":1700545386000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Heterogenized Molecular Electrocatalyst Based on a Hydroxo\u2010Bridged Binuclear Copper(II) Phenanthroline Compound for Selective Reduction of CO\n                    <sub>2<\/sub>\n                    to Ethylene"],"prefix":"10.1002","volume":"36","author":[{"given":"Na","family":"Liu","sequence":"first","affiliation":[{"name":"Leibniz Institute for Catalysis  Albert\u2010Einstein\u2010Str. 29a 18059 Rostock Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Bartling","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Catalysis  Albert\u2010Einstein\u2010Str. 29a 18059 Rostock Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armin","family":"Springer","sequence":"additional","affiliation":[{"name":"Electron Microscopy Center University Medicine Rostock  Strempelstr. 14 18057 Rostock Germany<?vsp -1pc?>"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Kubis","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Catalysis  Albert\u2010Einstein\u2010Str. 29a 18059 Rostock Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga S.","family":"Bokareva","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Catalysis  Albert\u2010Einstein\u2010Str. 29a 18059 Rostock Germany"},{"name":"Institute of Physics University of Kassel  Heinrich\u2010Plett\u2010Str. 40 34132 Kassel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evaristo","family":"Salaya","sequence":"additional","affiliation":[{"name":"Leibniz Institute for Catalysis  Albert\u2010Einstein\u2010Str. 29a 18059 Rostock Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiameng","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory for Liquid\u2013Solid Structural Evolution and Processing of Materials (Ministry of Education) School of Materials Science and Engineering Shandong University  Jingshi Rd. 17923 Jinan 250061 P.

Consequently the decrease of the Cu content in the electrode coating alone cannot explain the reduction of the intensity of the bands.
