Abstract
Abstract Electrochemical C−N coupling reaction based on carbon dioxide and nitrate have been emerged as a new “green synthetic strategy” for the synthesis of urea, but the catalytic efficiency is seriously restricted by the inherent scaling relations of adsorption energies of the active sites, the improvement of catalytic activity is frequently accompanied by the decrease in selectivity. Herein, a doping engineering strategy was proposed to break the scaling relationship of intermediate binding and minimize the kinetic barrier of C−N coupling. A thus designed SrCo 0.39 Ru 0.61 O 3−δ catalyst achieves a urea yield rate of 1522 μg h −1 mg cat. −1 and faradic efficiency of 34.1 % at −0.7 V versus reversible…
