Enriched and Sustained Oxygen Vacancies in Amorphous NiWOx Enhance and Stabilize Urea Electrooxidation

Angewandte Chemie, EarlyView.
We propose an “amorphous oxygen mechanism (AOM)” for urea electrooxidation on amorphous NiWOx with tunable Ov, which achieves robust UOR activity and stability simultaneously. The “amorphous oxygen” in NiWOx prefers to escape during the UOR, in situ generating and stabilizing Ov, which thermodynamically promotes the reaction.
