説明
<jats:title>Abstract</jats:title><jats:p>Designing effective electrocatalysts for the carbon dioxide reduction reaction (CO<jats:sub>2</jats:sub>RR) is an appealing approach to tackling the challenges posed by rising CO<jats:sub>2</jats:sub> levels and realizing a closed carbon cycle. However, fundamental understanding of the complicated CO<jats:sub>2</jats:sub>RR mechanism in CO<jats:sub>2</jats:sub> electrocatalysis is still lacking because model systems are limited. We have designed a model nickel single‐atom catalyst (Ni SAC) with a uniform structure and well‐defined Ni‐N<jats:sub>4</jats:sub> moiety on a conductive carbon support with which to explore the electrochemical CO<jats:sub>2</jats:sub>RR. Operando X‐ray absorption near‐edge structure spectroscopy, Raman spectroscopy, and near‐ambient X‐ray photoelectron spectroscopy, revealed that Ni<jats:sup>+</jats:sup> in the Ni SAC was highly active for CO<jats:sub>2</jats:sub> activation, and functioned as an authentic catalytically active site for the CO<jats:sub>2</jats:sub>RR. Furthermore, through combination with a kinetics study, the rate‐determining step of the CO<jats:sub>2</jats:sub>RR was determined to be *CO<jats:sub>2</jats:sub><jats:sup>−</jats:sup>+H<jats:sup>+</jats:sup>→*COOH. This study tackles the four challenges faced by the CO<jats:sub>2</jats:sub>RR; namely, activity, selectivity, stability, and dynamics.</jats:p>
