| 제목 | Strong Metal-Support Interaction (SMSI) in Pt/CeO2: Nature and Catalytic Activity |
| 초록 | Platinum group metals (PGMs) are widely used as catalytically active phase in catalyst. Their unique electronic d-band structure allows them to be applied in many kinds of different reactions including CO oxidation, methane oxidation, hydrogenation, and water-gas shift reaction. When PGMs are dispersed on support, they interact electronically with each other, which brings about the physiochemical effects on their catalytic properties. In this regard, metal-support interaction (MSI) between PGM and support has been an interesting topic of many research groups. Hence, understanding the metal-ceria interaction is of practical importance to provide the rational design of ceria supported PGM catalysts. In the present presentation, the interaction between Pt and CeO2 has been extensively investigated by combining various characterization methods. Especially, the effect of Pt-ceria interaction under the oxidizing/reducing environment on the thermal stability and the catalytic activity of Pt/CeO2 catalyst has been focused in detail. |
