摘　　要：金属载体强相互作用(SMSI)用于构建具有选择性的催化剂是一种非常有前景的方法。近年来,SMSI的发展为开发高性能的负载型多相催化剂开辟了新的途径。该效应导致金属与氧化物接触时,电子从氧化物转移到金属,以实现费米能级的平衡,形成富电子的活性位点。增加的界面密度有助于促进特定基本反应的催化活性,从而显著提高整体催化性能。SMSI不仅为设计和调控先进的多相催化剂提供了可能性,还在广泛应用中具有重要意义。本文综述了SMSI的研究进展,首先简要回顾了其发展历程,然后从提高催化剂活性、增强稳定性以及优化产物选择性三个方面概述了SMSI的反应机理。此外,文章总结了SMSI对催化性能的促进作用,并强调了基于SMSI开发催化剂调控策略的重要性,以扩展其应用领域。Strong metal-support interaction(SMSI)is a promising method for constructing selective catalysts.In recent years,the development of SMSI has opened up a new way for the development of high-performance supported heterogeneous catalysts.This effect leads to the transfer of electrons from the oxide to the metal when the metal is in contact with the oxide,so as to achieve the balance of the Fermi level and form an electron-rich active site.The increased interface density helps to promote the catalytic activity of specific basic reactions,thereby significantly improving the overall catalytic performance.SMSI not only provides the possibility for the design and regulation of advanced heterogeneous catalysts,but also has important significance in wide applications.In this paper,the research progress in SMSI is reviewed.Firstly,the development process of SMSI is briefly reviewed.Then,the reaction mechanism of SMSI is summarized from three aspects:improving catalyst activity,enhancing stability and optimizing product selectivity.In addition,this paper summarizes the promotion effect of SMSI on catalytic performance,and emphasizes the importance of developing catalyst regulation strategies based on SMSI to expand its application fields.
