CeO_x-Integrated dual site enhanced urea electrosynthesis from nitrate and carbon dioxide.

ABSTRACT: Electrocatalytic urea synthesis via the co-reduction of NO3- and CO₂ as a promising option to the conventional Bosch-Meiser remains challenged by regulating desired intermediates to simultaneously achieve a high yield and Faradaic efficiency. Here, we integrate the substrate material (SiO₂) and functionally atomic sites (Cu and Sn) utilizing CeO_x nanoclusters as 'adhesive', in which the CeO_x and SiO₂ form the composite carrier (CS) construct Cu and Sn diatomic electrocatalyst (CuSn/CS-1). Spectroscopic techniques and density functional theory calculations reveal that overall charge redistribution in the CeO_x-CuSn modules forms bifunctional active sites with unique electronic properties and abundant oxygen vacancies. The Cu s
