| Abstract: | Supported metal catalysts are important in many industrial reactions. It is reported that support materials are not always inert, and in some cases could even interact with metal nanoparticles (NPs) actively via various ways. In particular, the strong metal-support interaction (SMSI), referring to metal NPs covered by support materials, affects catalysis at the active sites on the metal NP surface, which can serve as a very effective method in tuning and improving catalytic performance. By tailoring the support materials or controlling the treatment processes, different kinds of SMSI, such as classical SMSI, oxidative SMSI, wet-chemistry SMSI, and adsorbate-mediated SMSI, can be achieved. This concept summarizes the general strategies to tune SMSI and discusses the key results. Moreover, a new proposal is presented to tailor SMSI by combining both the exposed facets of the support materials and external environments. Furthermore, the challenges faced at present are discussed and useful insights for future research concerning this topic are provided. |
