摘要
The electrochemical reduction of nitrogenous species (such as N2, NO, NO2-, and NO3-) for urea synthesis under ambient conditions has been extensively studied due to their potential to realize carbon/nitrogen neutrality and mitigate environmental pollution, as well as provide a means to store renewable electricity generated from intermittent sources such as wind and solar power. However, the sluggish reaction kinetics and the scarcity of active sites on electrocatalysts have significantly hindered the advancement of their practical applications. Multifunctional engineering of electrocatalysts has been rationally designed and investigated to adjust their electronic structures, increase the density of active sites, and optimize the binding energies to enhance electrocatalytic performance. Here, surface engineering, defect engineering, doping engineering, and heterostructure engineering strategies for efficient nitrogen electro-reduction are comprehensively summarized. The role of each element in engineered electrocatalysts is elucidated at the atomic level, revealing the intrinsic active site, and understanding the relationship between atomic structure and catalytic performance. This review highlights the state-of-the-art progress of electrocatalytic reactions of waste nitrogenous species into urea. Moreover, this review outlines the challenges and opportunities for urea synthesis and aims to facilitate further research into the development of advanced electrocatalysts for a sustainable future. This review provides an in-depth exploration of engineering modification strategies for catalytic materials and their promising applications in C & horbar;N coupling for urea electrosynthesis. Additionally, it highlights the significance of integrating diverse modification strategies to improve the efficiency of C & horbar;N coupling in urea synthesis. Finally, the review evaluates the potential challenges and opportunities that catalytic materials for C & horbar;N coupling may encounter in the path toward future commercialization. image
