Tuning the surface strain is a powerful strategy to enhance catalytic activity of metal nanocatalysts, yet an atomically precise catalyst with intramolecular unlock atomic-level strain-structure-activity relationship still highly desired. Herein, we report synthesis, structural anatomy, and performance toward cyclohexanone oxime electrosynthesis Ag16Cu18(C≡C-C6H11)24 (Ag16Cu18) nanocluster, which has Cu6 ring in center. The Cu-Cu distance only 1.616 Å single crystal, shortest bond Cu nanomaterials date. Furthermore, once Ag16Cu18 was loaded onto carbon paper, ultrashort elongated ∼2.40 Å, showing strong compressive strain. exhibited excellent electrosynthesis, manifested by maximal Faradaic efficiency, yield, yield rate reaching 47.4%, 95.4%, 2.66 mmol·h-1·cm-2 at -0.35 V, respectively. In-situ attenuated total reflection surface-enhanced infrared spectroscopy revealed that sites adjacent Ag atoms primarily reduce NO stabilize it *NH2OH stage, while provide H* for reduction adsorb react *NH2OH, forming simultaneously. Density functional theory calculations confirmed presence ring, facilitates formation adsorption, hence significantly contributing generation. This study not reports case clusters but also provides understanding employing bimetallic nanocluster-based catalysts valuable organic molecules.

Disrupting the charge distribution equilibrium in catalysts is an effective strategy for polarization and cleavage of small molecules during electrocatalytic process. To achieve C-C bond multicarbon molecules, such as glycerol, integrating advantages defect sites while creating spatially asymmetric that modulate local electronic perturbations both promising challenging. In this study, pairs were engineered by partially refilling sulfur atoms into spinel CuCo2Ox with a high oxygen vacancy density (HVo-S). These defect-refilled S (Vo-S) enhance transfer, reduce energy barrier glycerol adsorption, create thermodynamically favorable conditions second cleavage, whereas vacancies further amplifies perturbations. Exploiting spatial effects sites, HVo-S demonstrated superior performance compared to HVo without Vo refilling, achieving Faradaic efficiencies (FE) 98.5% 75.3% at 1.36 V vs RHE formic acid oxidation reaction (GOR), respectively. Significantly, also promotes electrooxidation ethylene glycol glucose, confirming its broad applicability activating bonds polyol substrates. This study elucidates role localized GOR process, providing new insights design novel electrocatalysts aimed promoting molecules.

N2 fixation into NH3 under ambient conditions remains greatly challenging, where a relay scheme by plasma-enabled oxidation (pN2OR) and the NO reduction reaction (NORR) can be practical route. However, efficient conversion of NO, as intermediate nitrogen energy carrier, has not been accomplished due to limited mass transfer in solution. Here, tandem pN2OR photocatalytic NORR route (N2-NO-NH3) is developed achieve sustainable synthesis with near-complete conversion. The highly concentrated (∼1%), produced via pN2OR, introduced an absorption-photocatalysis scheme, efficiencies for synchronous dissolution photoreduction are significantly promoted. This system delivers near 100% ratio superior selectivity (98.33% ± 0.75%) stability (240 h) single-pass continuous flow. research successfully profitable production route, yielding substantial profit $3000 per ton NH4COOH final product.
