Atomically precise metal nanoclusters (NCs) have emerged as an intriguing class of model catalysts for electrochemical CO2 reduction reactions (CO2RR). However, the interplay between interface environment (e.g., potential, cation concentration) and electron–proton transfer (ET/PT) kinetics─particularly in alkynyl-protected NCs─remains poorly understood. Here, we combined first-principles simulations experiments to investigate role potential effect on CO2RR performance a prototype all-alkynyl-protected Ag15(C≡C–CH3)+ cluster. Our revealed that applied triggers elimination alkynyl ligand via sequentially breaking two π-type Ag–C bonds one σ-type bond expose catalytically active Ag sites, barrier breakage monotonically decreases with lowering potential. Furthermore, show introducing inner-sphere Na+ ions greatly enhances *CO2 activation promotes proton generate *COOH *CO by forming Na+–CO2(*COOH) complexes, while competitive hydrogen evolution reaction (HER) from water dissociation is suppressed, thus dramatically improving selectivity electroreduction. The measurements further validated our predictions, where CO Faradaic efficiency (FECO) current density (jCO) pronounced dependence concentration. At optimal concentration 0.1 M NaCl, FECO can reach up ∼96%, demonstrating crucial cations promoting CO2RR. findings provide vital insights into atomic-level mechanism Ag15 NCs highlight important electrolyte governing electron/proton kinetics.

Polymeric ionomers near the catalyst surface of CO2 reduction reaction (CO2RR) electrodes affect their efficiency; however, multifaceted properties complicate structure–activity relationship elucidation. Here, we synthesized polycarbazole-based anion-exchange (QPC) bearing varying functionalized side chains to explore this relationship. Comprehensive analysis in physicochemical properties, electrochemical activity, and operando ATR-SEIRAS revealed that functional group modification significantly influenced intrinsic ionomer thereby affecting Ag microenvironments interfacial water structures, kinetics protonation step for CO2RR hydrogen evolution (HER). Notably, QPC-trimethyl phosphonium (TMP) induced favorable having a high proportion strong H-bonded with low Stark tuning slopes, which inhibit HER promote CO2RR. A CO Faradaic efficiency (>90%) was maintained using QPC-TMP membrane electrode assembly, even under concentrations (100–15%) elevated temperatures (28–72 °C). These findings suggest catalytic environment can be optimized by fine-tuning structure, contributing advancement high-performance ionomers.

Ligand-protected copper nanoclusters (Cu NCs) with atomic precision have emerged rapidly due to their fascinating structural architectures and versatile catalytic properties, making them ideal for investigating structure-activity relationships. Despite potential, challenges such as stability issues limited diversity restricted deeper exploration. In this study, three distinct Cu NCs are synthesized using a one-pot reduction strategy by carefully modifying reaction conditions. Intriguingly, the same p-toluenethiol ligand produces two different geometries, while varying ligands m-aminobenzethiol-yielded clusters similar geometric architectures. These evaluated electrocatalytic CO2 reduction, uncovering diverse activities product selectivity. Experimental theoretical analyses reveal that interplay between core structure confinement surface environment governs behavior. Specifically, Cu11 NC exhibits selectivity toward HCOOH production (FEHCOOH∼45% at -1.2 V vs RHE), whereas substituting m-aminobenzethiol shifted competitive side (FEH2∼82% RHE). Conversely, altering geometry of Cu18 retaining decreases (FEHCOOH∼35% findings highlight tunability tailored applications through precise control chemistry.
