Anion-Directed Assembly of a Bimetallic Pd/Ag Nanocluster: Synthesis, Characterization, and HER Activity

Molecules, Journal Year: 2025, Volume and Issue: 30(2), P. 404 - 404

Published: Jan. 18, 2025

Palladium-doped silver nanoclusters (NCs) have been highlighted for their unique physicochemical properties and potential applications in catalysis, optics, electronics. Anion-directed synthesis offers a powerful route to control the morphology of these NCs. Herein, we report novel Pd-doped Ag NC, [Pd(H)Ag13(S){S2P(OiPr)2}10] (PdHAg13S), synthesized through inclusion sulfide hydride anions. This NC features linear S-Pd-H axis enclosed 4-5-4 stacked arrangement atoms. The distinctive environment was characterized by NMR spectroscopy, total structure determined single-crystal X-ray diffraction (SCXRD) supported computational studies. Mass spectrometry photoelectron spectroscopy (XPS) further confirmed assigned composition. construct exhibits promising hydrogen evolution reaction (HER) activity. Our findings highlight anion-directed creating bimetallic NCs with tailored structures catalytic properties.

Few-Atom Copper Cluster Facilitates H₂O₂ Activation to Promote Selective Oxidation of Benzene to Phenol

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 3, 2025

The catalytic oxidation of benzene faces challenges in achieving high activity and selectivity. While single-atom catalysts present intriguing potential for this transformation, their practical implementation is hindered by intrinsic limitations the mass-specific activity. In context, few-atom cluster have emerged as an alternative, leveraging well-defined metal ensemble effects that enable precisely tailored active sites enhanced interatomic synergies. Herein, we introduce atomic supported on a graphitic carbonitride (CN) catalyst (Cu3/CN), exhibiting excellent performance selective to phenol, with superior turnover frequency (TOF) Cu1/CN (719 h-1 vs 280 h-1) suppressing phenol selectivity nanoparticle CuNP/CN (95.3% 77.2%). Multimodal mechanistic investigations unambiguously identify critical role adsorbed O* Cu site (Cu═O*) C-H-oxidation, verified both situ spectroscopic monitoring ex surface analysis. Complementary density functional theory calculations validate (Cu3) features higher d-band center larger charge transfer H2O2 molecule than isolated Cu1 site. sufficient stretches O-O bond facilitate formation Cu═O* species. Furthermore, resulting Cu3 demonstrates significant hybridization O 2p orbitals 3d at Fermi level, which endows it activation. appropriate effect unique architecture key its performances. This work establishes structure-performance correlation highlights optimizing functionality.
