摘要: 强金属-载体相互作用(SMSI)在催化研究中占据核心地位,其在负载型金属催化材料的性能调控过程中起着关键作用。SMSI效应的引入改善了负载型催化剂中活性金属组分的几何结构和电子结构,可提高催化活性和目标产物选择性,并增强催化剂的稳定性。详细阐述了SMSI效应的表征技术、典型特征、构筑策略及其适用场景,回顾了SMSI效应在能源转化、环境保护和精细化学品合成领域的应用进展,探讨了其催化作用机制。未来,需开发更高效的表征技术以深入揭示SMSI效应的形成机制。此外,应拓展SMSI效应的应用领域,以满足不同工业场景和环境的催化需求。

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.
