説明
<jats:title>Abstract</jats:title><jats:p>Reported here is the chelate effect as a design principle for tuning heterogeneous catalysts for electrochemical CO<jats:sub>2</jats:sub> reduction. Palladium functionalized with a chelating tris‐N‐heterocyclic carbene (NHC) ligand (Pd‐timtmb<jats:sup>Me</jats:sup>) exhibits a 32‐fold increase in activity for electrochemical reduction of CO<jats:sub>2</jats:sub> to C1 products with high Faradaic efficiency (FE<jats:sub>C1</jats:sub>=86 %) compared to the parent unfunctionalized Pd foil (FE=23 %), and with sustained activity relative to a monodentate NHC‐ligated Pd electrode (Pd‐mimtmb<jats:sup>Me</jats:sup>). The results highlight the contributions of the chelate effect for tailoring and maintaining reactivity at molecular‐materials interfaces enabled by surface organometallic chemistry.</jats:p>
