Prior experimental studies showed that introducing pendant amines in the secondary coordination sphere of the catalyst shifts product selectivity from CO to HCOO<sup>\u2013<\/sup>\u00a0(in the presence of a proton source) in the case of Mn. In contrast, CO is the major product with Re and Ru. This work includes a comprehensive study of the pathways leading to CO, HCOO<sup>\u2013<\/sup>, and H<sub>2<\/sub>\u00a0to elucidate the energetic preferences that underlie product selectivity. Our results show that switching the metal center leads to changes in the preferred mechanism. While with Mn, the reaction is preferred in an\u00a0<em>endo<\/em>\u00a0configuration, allowing the participation of amines in the hydride formation, reactivity on the\u00a0<em>exo<\/em>\u00a0configuration is preferred with Re. In addition, the distinct redox properties of Re allow for the formation of Re OCOCO<sub>2<\/sub>-bridged adducts that lead to CO without a proton source. Further, the ability of Ru to exchange the two Cl<sup>\u2013<\/sup>\u00a0anions changes the preferred coordination number of Ru compared to Mn and Re and, consequently, its reaction mechanism. Overall, this study provides the structure and reactivity insight needed for further catalyst design.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Title:Metal-Dependent Mechanism of the Electrocatalytic Reduction of CO2\u00a0by Bipyridine Complexes Bearing Pendant Amines: A DFT Study Abstract:In this study, the electrocatalytic reduction of carbon dioxide &hellip;<\/p>\n","protected":false},"author":514,"featured_media":3665,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[8],"tags":[],"class_list":["post-3664","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research"],"_links":{"self":[{"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/posts\/3664","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/users\/514"}],"replies":[{"embeddable":true,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/comments?post=3664"}],"version-history":[{"count":2,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/posts\/3664\/revisions"}],"predecessor-version":[{"id":3673,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/posts\/3664\/revisions\/3673"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/media\/3665"}],"wp:attachment":[{"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/media?parent=3664"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/categories?post=3664"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/site.uit.no\/nordco2\/wp-json\/wp\/v2\/tags?post=3664"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
