Pairing N‐Vacancy and Adjacent Ni‐Sites in the Local Microenvironment to Regulate the Urea Oxidation Reaction Pathway With Enhanced Kinetics

Advanced Materials, EarlyView.
In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...
