Abstract:
The concept of strong metal-support interaction (SMSI), a topic of investigation for over four decades, remains an important area of research in heterogeneous catalysis. While substantial progress has been made in understanding SMSI across various metal/support systems, its complexity continues to evolve. TiO2, recognized as the first support material to exhibit SMSI, has been instrumental in advancing this understanding. However, the lack of a comprehensive guide on how various factors influence SMSI on TiO2 has limited the ability to systematically control these interactions. This review seeks to provide a consolidated view of the current understanding of SMSI in TiO2-supported metal catalysts. It highlights the sensitivity of SMSI on TiO2 to a range of parameters, including pretreatment conditions and reaction environments. The dynamic nature of SMSI under reaction conditions is also explored, underscoring its complexity and potential for fine-tuning catalyst performance. Additionally, practical insights into innovative chemical methods for controlling SMSI on TiO2 are discussed, offering strategies for modulating SMSI to meet specific catalytic requirements. By addressing these aspects, this review aims to offer a valuable guide for the rational design of metal/TiO2 catalysts, ultimately contributing to a more refined and controllable approach to SMSI on TiO2.
