CeO <sub>2</sub> promotes oxygen vacancy generation in Co(OH) <sub>2</sub> for enhanced water oxidation
A comparative study of CeO<sub>2</sub>-decorated Co(OH)<sub>2</sub> and CoOOH highlights the critical role of substrate dynamics. Operando spectroscopic studies reveal that the interface derived from Co(OH)<sub>2</sub> efficiently stabilizes oxygen vacancies. Such vacancy stabilization promotes the formation of high-valent CoO<sub>2</sub> species, thereby enhancing oxygen evolution performance.
