Oxygen Vacancy-Mediated Selective C-N Coupling toward Electrocatalytic Urea Synthesis

Xiaoxiao Wei et al.

Summary: This study proposes a new method for synthesizing urea at ambient conditions, which improves the efficiency of the C-N coupling reaction by stabilizing the crucial intermediate through the insertion of oxygen vacancies. The existence of oxygen vacancy-mediated selective C-N coupling reaction is verified through in situ spectroscopy techniques. The introduction of oxygen vacancies transforms the common catalyst carrier into an efficient electrocatalyst, with a higher urea yield rate compared to partial noble-metal-based electrocatalysts.
