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.

Thermo-catalytic CO 2 hydrogenation to high-value oxygenates has been regarded as one of the most powerful strategies that can potentially alleviate excessive CO 2 emissions. However, due to the high chemical stability of CO 2 and the variability of hydrogenation pathways, it is still challenging to achieve highly active and selective CO 2 hydrogenation. Single atom catalysts (SACs) with ultrahigh metal utilization efficiency and extraordinary electronic features have displayed growing importance for thermo-catalytic CO 2 hydrogenation with multiple strategies developed to improve performances. Here, we review breakthroughs in developing SACs for efficient CO 2 hydrogenation toward common oxygenates (CO, HCOOH, CH 3 OH, and CH 3 CH 2 OH) in the following order: first, an analysis of reaction mechanisms and thermodynamics challenges of CO 2 hydrogenation reactions; second, a summary of metal SAs designed by dividing them into the two categories of the single-and dual-sites; third, discussion of support effects with a focus on approaches to regulating strong metal−support interaction (MSI). Summarily, current challenges and future perspectives to develop higher-performance SACs in CO 2 hydrogenation are presented. We expect that this review can bring more design inspiration to trigger innovation in catalytic CO 2 evolution materials and eventually benefit the achievement of the carbon-neutrality goal.
