Abstract
Abstract Electrocatalytic CN coupling between carbon dioxide and nitrate has emerged to meet the comprehensive demands of carbon footprint closing, valorization of waste, and sustainable manufacture of urea. However, the identification of catalytic active sites and the design of efficient electrocatalysts remain a challenge. Herein, the synthesis of urea catalyzed by copper single atoms decorated on a CeO 2 support (denoted as Cu 1 –CeO 2 ) is reported. The catalyst exhibits an average urea yield rate of 52.84 mmol h −1 g cat. −1 at −1.6 V versus reversible hydrogen electrode. Operando X‐ray absorption spectra demonstrate the reconstitution of copper single atoms (Cu 1 ) to clusters (Cu 4 ) during…
