Strong Metal-Support Interactions of Metal/Meatal Oxide Catalysts

Catalysis plays an important role in the modern chemical industry, and developing catalyst with high efficiency is one of the important targets in catalysis research. Due to the outstanding activity of those catalysts with strong metal-support interactions ( SMSI), SMSI has become an important scientific topic in catalysis research. The SMSI phenomenon involves the encapsulation of the metal nanoparticles ( NPs) by support, resulting in the improved stabilization of NPs, and the different catalytic performances due to the new interaction between NPs and the support. Currently, a great number of catalysts with SMSI have been designed and partially applied, also there are considerable literatures focusing on SMSI of supported catalysts, especially those using metal oxide for support. However due to the complexity, the nature of SMSI and the catalytic mechanism of SMSI deserve further study, and the argument about the driving force of SMSI formation still exists. This review summarizes the recent progress, effect, and the regulation of SMSI, hopefully providing the understanding of SMSI from the perspective of condensed matter chemistry, and a new strategy of catalyst design.
