Abstract: Strong metal-support interaction (SMSI) occupies a core position in catalysis research and plays a crucial role in modulating the performance of metal-supported catalysts. By changing the geometric structuresand electronic structures of the active metal components in supported catalysts, the SMSI effect can enhance catalytic activity and selectivity for target products, as well as improve catalyst stability.A detailed discussion on the characterization techniques, typical features, construction strategies, and applicable scenarios of the SMSI effect was presented. The progress of SMSI in the fields of energy conversion, environmental protection, and fine chemical synthesis were reviewed, and its catalytic mechanisms was explored. In the future, more efficient characterization techniques need to be developed to deeply reveal the formation mechanism of SMSI effect. In addition, the application areas of SMSI effect should be expanded to meet the catalysis needs of different industrial scenarios and environments.
