Abstract
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 of CO2 and NO3– on the copper surface limits the interaction of the key carbon and nitrogen intermediates, thereby impeding efficient C–N coupling. In this study, we demonstrate that the residual lattice oxygen in oxide-derived copper nanosheets (OL-Cu) can effectively tune the electron distribution, thus activating neighboring copper atoms and generating electron-deficient copper (Cuδ+) sites. These Cuδ+ sites enhance CO2 adsorption and stabilize *CO intermediates, which enables the…
