Lattice Oxygen-Driven Co-Adsorption of Carbon Dioxide and Nitrate on Copper: A Pathway to Efficient Urea Electrosynthesis

Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Фев. 10, 2025

The electrochemical coupling of CO2 and NO3– on copper-based catalysts presents a sustainable strategy for urea production while simultaneously addressing wastewater denitrification. However, the inefficient random adsorption copper surface limits interaction key carbon nitrogen intermediates, thereby impeding efficient C–N coupling. In this study, we demonstrate that residual lattice oxygen in oxide-derived nanosheets (OL-Cu) can effectively tune electron distribution, thus activating neighboring atoms generating electron-deficient (Cuδ+) sites. These Cuδ+ sites enhance stabilize *CO which enables directional at adjacent This mechanism shortens pathway achieves yield up to 298.67 mmol h–1 g–1 −0.7 V versus RHE, with an average Faradaic efficiency 31.71% high current density ∼95 mA cm–2. situ spectroscopic measurements confirmed formation tracked evolution intermediates (i.e., *CO, *NO, *OCNO, *NOCONO) during synthesis. Density functional theory calculations revealed promote coadsorption *NO3, as well *OCNO significantly improving kinetics. study underscores critical role facilitating selectivity.
