Polycrystalline copper or large copper particles are well‐known to catalyze CO2 reduction to hydrocarbons at relatively negative potentials, or when their surface is covered by copper oxides (Cu2O and CuO). Cu‐based materials modified by various palladium contents (0<×<100), were synthesized by using the microwave‐assisted polyol method to serve as a cathode in the selective CO2‐into‐HCOOH transformation. Herein, we developed a targeted preparation route toward the metal content/catalytic activity relationship correlating atomic ratio with faradaic efficiency (FE) to formate formation (ca. 60 % FE) at −0.72 V vs. RHE, which represents a 703 mV overpotential at pH=7. Consequently, the occurrence of this reduction reaction slows down the parallel H2 production from the solvent consumption, while the neighboring Cu−Pd provides excellent activity and a good efficiency toward CO2 reduction via the hydridation of the CO2 molecule to orientate the reaction to formate rather than carbon monoxide or H2 evolution.
Pick and choose: Selective CO2‐to‐HCOOH conversion occurs at the surface carbon‐supported CuxPd100‐x nanoparticles. Higher faradaic efficiency (ca. 60 %) is obtained on Cu50Pd50/C at −0.72 V vs. RHE, where low parallel H2 and CO production occurs.</description><identifier>ISSN: 2196-0216</identifier><identifier>EISSN: 2196-0216</identifier><identifier>DOI: 10.1002/celc.202100268</identifier><language>eng</language><publisher>Weinheim: John Wiley & Sons, Inc</publisher><subject>Bimetals ; Carbon ; Carbon dioxide ; carbon dioxide reduction ; Carbon monoxide ; Catalytic activity ; Cathodes ; Chemical reduction ; Conversion ; Copper ; Copper oxides ; Electrode materials ; formate ; formic acid ; Hydridation ; Hydrogen evolution ; Hydrogen production ; microwave synthesis ; Nanoparticles ; Palladium ; palladium-copper nanoparticles</subject><ispartof>ChemElectroChem, 2021-04, Vol.8 (7), p.1362-1368</ispartof><rights>2021 Wiley‐VCH GmbH</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><orcidid>0000-0002-5379-7792</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fcelc.202100268$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fcelc.202100268$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,777,781,1412,27905,27906,45555,45556</link.rule.ids></links><search><creatorcontrib>Şahin, Nihat Ege</creatorcontrib><creatorcontrib>Comminges, Clément</creatorcontrib><creatorcontrib>Arrii, Sandrine</creatorcontrib><creatorcontrib>Napporn, Teko W.</creatorcontrib><creatorcontrib>Kokoh, Kouakou B.</creatorcontrib><title>CO2‐to‐HCOOH Electrochemical Conversion on Nanostructured CuxPd100−x/Carbon Catalysts</title><title>ChemElectroChem</title><description>Selective electrochemical conversion of CO2 to HCOOH is obtained at the surface of a carbon‐supported bimetallic cathode material composed of copper and palladium nanoparticles.
