Urea is widely used as fertilizer and is a key substance supporting global food production.However,the traditional industrial synthesis of urea faces the challenges with high energy consumption and serious environmental problems.With the increasing global demand for environmental protection and sustain-able development,it is much necessary to develop novel and clean methods for the synthesis of urea.Electrocatalysis provides an efficient and renewable synthesis route that can directly produce urea at room temperature and atmospheric pressure by the coupling of CO2 and nitrogenous molecules.In this review,we summarized the most recent advances in electrochemical synthesis of urea via C-N coupling systematically,focusing on the coupling of CO2 and different nitrogen sources.And the associated cou-pling mechanism,catalysts optimization,and electrolyzer design are well discussed.Moreover,the chal-lenges and future directions for electrocatalytic C—N coupling are prospected.This review will provide timely and valuable guidance for others and attract more interests to promote the development of elec-trochemical synthesis of urea or other valuable chemicals containing C—N bond.
