Abstract: Supported Pt-based catalysts have demonstrated significant potential for various catalytic processes; however, simultaneously achieving high efficiency and thermal stability remains a major challenge in catalyst design, particularly under reducing reaction conditions. Herein, we fabricated 1Pt/10Y-MnO x (Mnδ+, 2 < δ < 3) catalyst, in which Y 2 O 3 -induced dual-functional interactions, comprising metal-support interaction (MSI) and oxide-support interaction (OSI), were regulated to modify the interfacial structures. On one hand, the embedded Pt-Y 2 O 3 MSI improved the catalyst resistance to Pt sintering as well as optimized the sorption behavior via electronic modification; On the other hand, the Y 2 O 3 -MnO x OSI promoted the generation of O v structures by stretching the Mn–O bonds and thereby enhanced the adsorption and activation for O-containing molecules, such as CO 2. Consequently, the 1Pt/10Y-MnO x catalyst exhibited outstanding CO production activity of 482.6 × 10−5 mol·g cat −1·s−1 for the reverse water-gas shift (RWGS) reaction at 600 °C, together with sustained long-term stability over 300 h. This work validates an approach to catalyst interfacial engineering via bifunctional interactions, thereby paving the way for designing highly active and stable Pt-based catalysts. [Display omitted] • The 1Pt/10Y-MnO x RWGS catalyst achieves a remarkable reactivity of 4.83 mmol·g−1·s−1 at 600 °C with an excellent stability over 300 h. • The embedded Pt-Y 2 O 3 interface structure anchors small Pt nanoparticles without sacrificing active site accessibility. • The Y 2 O 3 -MnO x oxide-support interaction promotes oxygen vacancy formation, thereby markedly enhancing CO 2 activation.
