Modulating C _<b>2</b> Selectivity in CO _<b>2</b> Electroreduction through Molecular Surface Engineering of Copper Nanowires.

ABSTRACT: Electrocatalytic reduction of CO₂ to multicarbon products represents a key target in the development of artificial (photo)-synthetic systems. Copper-based electrodes are uniquely suited for this purpose, yet achieving high selectivity toward C-C coupled products such as ethylene, over undesired byproducts like methane and hydrogen, remains a major challenge. Surface engineering has emerged as a powerful strategy to steer the selectivity of CO₂ electroreduction toward ethylene. Here, we introduce a modular hybrid electrode architecture composed of copper nanowires (CuNWs) coated with a thin, functional organic shell formed via electroreduction of ethylene-bridged dipyridophenazine (dppz) dication derivatives. This core-shell architecture enables fine-tuning of t
