Single-atom tailored atomically-precise nanoclusters for enhanced electrochemical reduction of CO₂-to-CO activity

Y. Wang, F. Yan, et al.

Discover how the innovative co-electropolymerization strategy led by Yi-Man Wang, Fang-Qin Yan, Qian-You Wang, Chen-Xia Du, Li-Ya Wang, Bo Li, Shan Wang, and Shuang-Quan Zang resulted in Au8 nanoclusters with extraordinary CO2 reduction capabilities, showcasing an astonishing ~18.07 fold increase in activity compared to isolated clusters, all while enhancing stability through single-atom functionalization.

Abstract
This paper reports the synthesis of well-defined Au8 nanoclusters modified by single-atom sites via a co-electropolymerization strategy. The resulting catalysts, denoted as Poly-(Au8-DCP@M) (M = Fe, Co, Ni, Cu, Zn), show significantly enhanced electrocatalytic reduction of CO2 to CO activity (~18.07 fold compared to isolated Au8 clusters). This enhancement is attributed to the altered electronic structures of Au8 clusters due to the single-atom functionalization, which optimizes the adsorption of key intermediates and establishes a favorable reaction pathway. The immobilization of nanoclusters and single atoms on a cross-linked polymer network also improves stability by preventing agglomeration.
