Abstract
Abstract In essence, electrocatalytic CO 2 reduction reaction (CO 2 RR) process for the CO 2 ‐to‐CO conversion involves two critical reactive intermediates: *COOH and *CO. The trade‐off between the adsorption of *COOH and the desorption of *CO is challenging for Ni‐based CO 2 RR catalysts. The high‐valence Ni site is inadequate in supplying sufficient electrons for CO 2 activation and subsequent adsorption of *COOH; conversely, the metallic Ni site with abundant electron exhibits excessively strong π‐backbonding with *CO, thus hindering its desorption. Here, the study reports a low‐coordinated Ni single atom catalyst (SAC) characterized by a low‐coordinated structure with carbon coordination, thereby…
