abstract = {Metal oxide supported metal catalysts show promising catalytic performance in many industry-relevant reactions. However, the enhancement of performance is often limited by the insufficient metal/metal oxide interface. In this work, we demonstrate a general synthesis of Pt-early transition metal oxide (Pt-MOx, M = Ti, Zr, V, and Y) catalysts with rich interfacial sites, which is based on the air-induced surface segregation and oxidation of M in the supported Pt-M alloy catalysts. Systematic characterizations verify the dynamic structural response of Pt-M alloy catalysts to air and the formation of Pt-MOx catalysts with abundant interfacial sites. The prepared Pt-TiOx interfacial catalysts exhibit improved performance in hydrogenation reactions of benzaldehyde, nitrobenzene, styrene, and furfural, as a result of the heterolytic dissociation of H2 at Pt-metal oxide interfacial sites.}
