On the Tracks to “Smart” Single-Atom Catalysts

Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

Despite their enormous impact in modern heterogeneous catalysis, single-atom catalysts (SACs) continue to puzzle the catalysis community, which often struggles draw correct conclusions SAC-catalyzed experiments. In many cases, reasons for such an uncertainty originate from lack of knowledge exact evolution under operative conditions and fundamental factors controlling fate single atom relation catalytic mechanism. This has led confusion also about definition terminology, where coined term

Engineering Atomic Sites and Proton Transfer Microenvironments for Bioinspired Photocatalytic Alcohol‐Amine Coupling

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 21, 2025

Achieving a precise understanding and accurate design of heterogeneous catalysts based on bioinspired principles is challenging yet crucial to digging out optimal materials for artificial catalysis. Here, an ADH-mimicking dual-site photocatalyst (YCuCdS) developed, demonstrates the powerful effects atomic site configuration proton transfer environments alcohol-amine coupling. Mechanism studies reveal that alcohol substrate effectively dehydrogenated at Y sites, forming carbonyl intermediates rapidly experience condensation with amine. Meanwhile, released hydrogen species (Hads) migrate from adjacent Cu sites active S atoms, promoting H2 production hindering over-hydrogenation imine. As result, high imine yield 92% achieved, along rate 7400 µmol g-1 h-1. This work showcases effective strategy bioinspiration.

Palladium Hydride Anchored on SrTiO₃ with Efficient Charge Separation and Surface Reaction Kinetics for Enhanced Photocatalytic Overall Water Splitting

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Апрель 14, 2025

Cocatalyst engineering is critical for advancing photocatalysis, as it suppresses charge carrier recombination, promotes interfacial electron/hole extraction, and serves active sites redox reactions. However, the incompatibility existing between cocatalyst host photocatalyst, along with its intrinsic properties of sites, limits further improvements in separation, surface reaction kinetics, overall performance. Herein, we introduce palladium hydrides (PdHx) an efficient on SrTiO3 (STO) photocatalytic water splitting, owing to their similar lattice parameters. The constructed PdHx/STO demonstrates a remarkable 6.4-fold enhancement hydrogen evolution compared Pd/STO control, reaching rate 5 mmol·g-1·h-1 at stoichiometric H2/O2 ratio 2:1. Structural characterizations theoretical analyses prove that situ formed PdHx feature advantages accelerated electron extraction modulated adsorption energies evolution; femtosecond transient absorption spectroscopy reveals prolonged lifetime improved transfer efficiency.
