Title: Strong Metal-support Interactions Volume of ACS symposium series, ISSN Volume of American Chemical Society: ACG symposium series: Authors: R. Strong metal–support interaction (SMSI) has gained great attention in the field of heterogeneous catalysis. However, whether single‐atom catalysts can exhibit SMSI remains unknown. Here, we demonstrate that SMSI can occur on TiO2‐supported Pt single atoms but at a much higher reduction temperature than that for Pt nanoparticles (NPs).Cited by: 3. Strong metal–support interactions (SMSI) are effective in tuning the structures and catalytic performances of catalysts but limited by the poor exposure of active sites. Here, the authors develop a. Highly transparent and active Pt–Mo2C counter electrodes were successfully fabricated by the strong metal–support interaction, with high dispersity of Pt nanoclusters on Mo2C support, which endowed bifacial dye-sensitized solar cells with a rear-to-front efficiency ratio as high as
This strong metalupport interaction is discussed in terms of the need for a reducible, transition metal oxide support and on the basis of bonding mechanisms suggested by known compounds. INTRODUCTION A fundamental property of the Group VIII noble metals is their ability to chemisorb hydrogen and carbon monoxide. Encapsulation of metal nanocatalysts by support-derived materials is well known as a classical strong metal–support interaction (SMSI) effect that occurs almost exclusively with active oxide supports and often blocks metal-catalyzed surface reactions. In the present work this classical SMSI process has been surprisingly observed between metal nanoparticles, e.g., Ni, Fe, Co, and Ru, and. Vol. 20, Strong Metal-Support Interactions Figure 1.

A bar representing nm is . covered class of metal-support inter-actions. Theinteractions appearto differ significantly in type and degree from those previously reported. In addition, the sizes and shapes of the metal parti-cles in these systems indicate the exis-tence of strong bonding. These "strong metal-support interaction" (SMSI) cata-lysts are underinvestigation for.
Harnessing strong metal–support interactions via a reverse route Show authors by Peiwen Wu, Shuai Tan, Jisue Moon, Zihao Yang, Victor Xinhua Fung, Naiyi Li, Shi-ze Yang, Yongqiang Cheng, Carter Abney, Zili Wu, Aditya Savara, Ayyoub Mehdizadeh Momen, De-en Jiang, Dong Su, Huaming Li, Wenshuai Zhu, Sheng Dai, Huiyuan Zhu. However, the extent of electron transfer seems quite small and the screening high with respect to neighboring atoms; 2) Morphological and topological features of surface metal sites are strongly affected by the so-called Strong Metal Support Interaction (SMSI). Strong metal–support interaction (SMSI) has gained great attention in the field of heterogeneous catalysis. However, whether single‐atom catalysts can exhibit SMSI remains unknown. Here, we demonstrate that SMSI can occur on TiO 2 ‐supported Pt single atoms but at a much higher reduction temperature than that for Pt nanoparticles (NPs). Many commercially important catalysts consist of small metal particles dispersed on inorganic oxide surfaces. Although in most cases there is no significant interaction between the metal and the support, strong bonding can be demonstrated in a recently discovered class of supported-metal catalysts. These cases typically involve group VIII metals dispersed on transition metal oxides whose.
