Building adaptive active sites in doped-RuO2 to boost acidic water oxidation performance

In this issue of Chem Catalysis, Zhu, Luo, and coworkers report Ce-doped RuO2 (Ce-RuO2-x) in which a synergistic effect between the Ce-O-Ru local structure and existing oxygen vacancies can allow the boosting of the acidic water oxidation activity and stability through an adsorption evolution mechanism.

Manipulating reaction pathway of ruthenium oxide with enhanced performance and stability toward acidic water oxidationWu et al.Chem CatalysisMay 20, 2024In BriefA Ce-doped RuO2 catalyst with the existence of oxygen vacancies is developed toward highly efficient and stable oxygen evolution electrocatalysis under acidic media. The Ce-O-Ru local environment and oxygen vacancies can not only contribute to stabilizing the OOH∗ intermediate and lead to manipulating the reaction pathway from LOM to AEM but also suppress surface Ru demetallation and lattice oxygen loss.
