The asymmetric oxygen vacancies on the surface of doped oxides and at interface between metal oxide are commonly regarded as real active sites for molecular activation reaction, owing to their unique electronic perturbation properties. However, essential rules modulating local structure promote capacity still ambiguous. In this work, a series interfacial vacancy sites, Pt/Ce–Ov–M (Ov, vacancy, M = Y, La, Pr, Nd), with different coordination environments were constructed based Pt/Ce0.95M0.05O2−δ materials. experimental data theoretical calculation results prove that site can capture electrons from Pt d-bands d- f-bands, acting an electron enrichment center. elevated d-band center upward Fermi level significantly boost transfer unoccupied π2p* orbital O2, achieving O2 through π-electron feedback mechanism. Remarkably, Pt/Ce–Ov–Y in Pt/Ce0.95Y0.05O2−δ highest delocalized density exhibited best behaviors catalytic activity aerobic oxidation 5-hydroxymethylfurfural. This work reveals over metal-oxide catalysts is highly dependent d/f-orbital valence-electron modulation, providing more insights into effect vacancy-localized performance.
