Abstract:<\/h4>\n
Manipulation C-C coupling pathway is of great importance for selective CO2<\/sub> electroreduction but remain challenging. Herein, two model Cu-based catalysts, by modifying Cu nanowires with Ag nanoparticles (AgCu NW) and Ag single atoms (Ag1<\/sub>Cu NW), respectively, are rationally designed for exploring the C-C coupling mechanisms in electrochemical CO2<\/sub> reduction reaction (CO2<\/sub>RR). Compared to AgCu NW, the Ag1<\/sub>Cu NW exhibits a more than 10-fold increase of C2<\/sub> selectivity in CO2<\/sub> reduction to ethanol, with ethanol-to-ethylene ratio increased from 0.41 over AgCu NW to 4.26 over Ag1<\/sub>Cu NW. Via a variety of operando\/in-situ techniques and theoretical calculation, the enhanced ethanol selectivity over Ag1<\/sub>Cu NW is attributed to the promoted H2<\/sub>O dissociation over the atomically dispersed Ag sites, which effectively accelerated *CO hydrogenation to form *CHO intermediate and facilitated asymmetric *CO-*CHO coupling over paired Cu atoms adjacent to single Ag atoms. Results of this work provide deep insight into the C-C coupling pathways towards target C2+<\/sub> product and shed light on the rational design of efficient CO2<\/sub>RR catalysts with paired active sites.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41467-024-54636-w Authors: Shifu Wang, Fuhua Li, Jian Zhao, Yaqiong Zeng, Yifan Li, Zih\u2010Yi Lin, Tsung-Ju Lee, Shu-Hui Liu, Xinyi Ren, Weijue Wang, Yusen Chen, Sung\u2010Fu Hung, Ying\u2010Rui Lu, Yi Cui, Xiaofeng Yang, Xuning Li, Yanqiang Huang, Bin Liu Abstract: Manipulation C-C coupling pathway is of great importance for selective CO2 electroreduction but remain challenging.
