Inside Back Cover: Deciphering and Suppressing Over‐Oxidized Nitrogen in Nickel‐Catalyzed Urea Electrolysis (Angew. Chem. Int. Ed. 51/2021)

Over-oxidation in alkaline urea oxidation to dominate NO2− formation over N2 has been discovered by Xuejing Yang, Yefei Li, Ming Gong, and co-workers in their Research Article on page 26656. The identified nitrogen conversion network and reaction mechanism has important implications for sustainable chemistry and inspires new rationales for novel catalyst designs for the electrochemical urea oxidation into N2 products.
