The strong metal-support interaction (SMSI) is one of the most important concepts in heterogeneous catalysis, which plays a crucial role modifying catalytic performance. However, study SMSI on single-atom catalysts (SACs), are considered to bridge homogeneous and remains preliminary. Here, best our knowledge, we first report oxidative SMSIs SACs utilize them enhance hydroformylation activity stability. surface-adsorbed Rh single atoms tend be encapsulated by ZrO2 supports after calcination air can re-exposed reduction H2. highest turnover frequency (TOF) reaches 11,097 h-1, surpassing previously reported SACs. embedded Rh, generated through SMSI, also shows enhanced stability resist metal leaching. Our work expands conceptual boundaries paves way for future design highly active stable catalysts.

Abstract Strong metal‐support interactions (SMSI) featuring the formation of encapsulation overlayer around metal nanoparticles has drawn much attention in heterogeneous catalysis. Recent years, various novel SMSI phenomena have been observed and nature also revealed with improvement characterization techniques. Understanding effect could deepen insight into structure‐activity relationship metal‐supported catalysts, rationally guide design special metal‐interface sites to manipulate catalytic behavior chemical reaction. In this review, research progress its application CO x hydrogenation are briefly surveyed, emphasis on advanced characterization, manipulation strategy specific role Fischer‐Tropsch synthesis process, 2 methanation Reverse Water Gas Shift The current challenges perspectives for development discussed.

Controllable metal-support interaction (MSI) modulations have long been studied for improving the performance of catalysts supported on metal oxides. However, corresponding in-depth study metal1-metal2 (M1-M2) composited configurations is rarely achieved due to lack reliable models and manipulation mechanisms MSI modifications. We modeled ruthenium copper support (Ru-Cu) with negligible interfacial contact potential (e0.06 V) investigated MSI-dependent hydrogen evolution reaction (HER) catalysis kinetics induced by an electronic hydroxyl (HO-) modifier. Comprehensive simulations characterizations confirmed that adjusting HO- coverage can readily realize tailorable improvement MSI, facilitating charge migration at Ru-Cu interface optimizing overall HER pathway active Ru. As a result, 5/10 monolayer (ML) HO-modified catalyst (5/10 ML) exhibits superior activity durability owing relatively stronger MSI. This also ensured sustainable efficient generation in urea electrolyzer significant energy savings. Our work provides valuable reference MSI-activity relationship M1-M2 target more than just HER.
