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.

Water electrolysis has been recognized as a promising technology that can convert renewable energy into hydrogen for storage and utilization. The superior activity low cost of catalysis are key factors in promoting the industrialization water electrolysis. Single-atom catalysts (SACs) have attracted attention due to their ultra-high atomic utilization, clear structure, highest evolution reaction (HER) performance. In addition, performance stability single-atom (SA) substrates crucial, various two-dimensional (2D) nanomaterial supports become foundations SA unique exposed surfaces, diverse elemental compositions, flexible electronic structures, drive single atoms reach limits. supported by 2D nanomaterials exhibits interactions synergistic effects, all which need be comprehensively summarized. This article aims organize discuss progress enhancing HER, including common widely used synthesis methods, advanced characterization techniques, different types supports, correlation between structural Finally, latest understanding was proposed.

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.
