Highlights: [•] WGS reaction on CeO2 (111)-supported Pt cluster follow both redox and associative carboxyl with redox regeneration mechanisms. [•] High activity of Pt/CeO2 interface sites originates from a significantly enhanced water activation and dissociation at interfacial oxygen vacancies. [•] First principles-based microkinetic modeling analysis provides insights on the unique activity of Pt/CeO2 interface. [ABSTRACT FROM AUTHOR]
