Abstract Using thiolate‐protected Au 25 (SR) 18 nanocluster (NC) with different charge states as the test candidate, how effect affects etching dynamics of thiolate ligands in acid and electrocatalytic performance is explored. The ab initio molecular (AIMD) simulations revealed charge‐dependent reaction kinetics acid, where anionic neutral (SCH 3 ) q (q = −1, 0) favorably react partially remove via two‐step proton attack, while cationic + NC acid‐resistant no tendency for ‐SR removal. Density functional theory (DFT) calculations further predict that dethiolated sites exhibit enhanced catalytic activity CO 2 electroreduction to CO, − showing significantly superior activity. Acid experiments confirmed partial removal 0), NCs electroreduction, particularly exhibiting better than 0 . This work an interesting state‐mediated interface behaviors NCs, which can be applied modulate properties other atomically precise metal nanoclusters.

Owing to its green energy and hydrogen sources, electrocatalytic semi-hydrogenation of alkynes is an attractive alternative for industrial alkene production. However, broad application hindered by low selectivity Faradaic efficiency (FE) due side reactions like over-hydrogenation alkanes. Here, we demonstrate that atomically precise Ag25(MHA)18 nanoclusters (NCs) can electrocatalyze alkyne with 98 % conversion, 99 selectivity, 85 FE, in a substrate pool. This achieved engineering the local environment at catalytically active sites. We leverage amphiphilic MHA (6-mercaptohexanoic acid) ligands pre-concentrate water molecules near ligand-layer/Ag25 interface. Long-chain disrupt hydrogen-bond network interface, high negative charge Ag25 attract weakly hydrogen-bonded through counterions promote generation (H*), while enzyme-like catalytic pockets on surface NCs facilitate adsorption terminal via σ-bonding Ag atoms. Density functional theory calculations confirmed preference model further revealed facile release product alkene. work not only exemplifies interface strategy control sites optimized activity selectivity.

Abstract Atomically precise copper(I) nanoclusters with stable active sites are highly sought‐after catalysts for the electrocatalytic CO₂ reduction reaction (CO₂RR), providing an exceptional platform to elucidate structure–activity relationships. However, rational synthesis of robust copper as effective electrocatalysts and understanding relationship between a more realistic site its performance remain significant challenge due their inherent instability. Here, novel dipropyne‐modified NHC ligand is elaborately devised two atomically nanoclusters, [Cu 17 H 6 (NHC ) 4 (dppm) ] 3+ ( Cu17a Ph Cu17b ), both exhibiting distinct unique square orthobicupola Cu core J 28 , Johnson solid). The σ‐ π‐bonding ligands imparts ultrahigh stability while coordination pattern μ 7 ‐ η σ 1 : π 2 facilitates exposure neighboring atoms, generating accessible catalytic sites. Electrocatalytic CO experiments show that achieves highest Faradaic efficiency ethylene production among reported nanoclusters. tandem mechanism RR elucidated through combination theoretical calculations attenuated total reflection‐surface‐enhanced IR absorption spectroscopy (ATR‐SEIRAS). This work not only introduces synthesizing but also offers critical insights into molecular design principles catalysts.

Abstract The modulation of traps has found attractive attention to optimize the performance luminescent materials, while understanding trap-involved photoluminescence management metal nanoclusters greatly lags behind, thus extensively impeding their increasing acceptance as promising chromophores. Here, we report an efficient passivation structural oxygen vacancies in AuAg by leveraging H 2 O molecules, achieving a sensitive color tuning from 536 480 nm and remarkably boosting quantum yield 5.3% (trap-state emission) 91.6% (native-state emission). In detail, favored electron transfer relevant contributes weak trap-state emission, which is capable being restrained molecules taking Au-O Ag-O bonds. This scenario allows dominated native-state emission with faster radiative rate. parallel, can rigidify landscape on hydrogen bonding, enabling suppression electron-optical phonon coupling decelerated non-radiative presented study deepens tailoring properties manipulating surface trap chemistry relaxation dynamics, would shed new light customizable performance.
