What are Strong Metal Support Interactions (SMSI)?
Strong Metal Support Interactions (SMSI) refer to a phenomenon where the properties of a metal catalyst are significantly altered due to the interaction with its support material. This interaction can lead to changes in electronic properties, structural modifications, and even changes in the catalyst's surface chemistry. SMSI is most commonly observed in catalysts where the metal is supported on reducible oxides such as TiO2, CeO2, and ZrO2.
