Atomically Precise Metal Nanoclusters and Single-Atom Catalysts for Selective Hydrogenation and Oxidation
This community investigates the design and synthesis of metal catalysts at the atomic and sub-nanometer scale to achieve high selectivity in chemical reactions, specifically hydrogenation and oxidation processes.
The work centers on gold, silver, copper, and palladium nanoclusters and single-atom sites, often stabilized by ligands or supported on metal oxides. Recurring applications include the selective hydrogenation of acetylene, cinnamaldehyde, and nitroarenes, as well as the selective oxidation of benzyl alcohol. Researchers focus on controlling active sites, metal-support interactions, and atomically precise structures to optimize catalytic activity and efficiency. The field also explores the photoluminescent properties of these nanoclusters, particularly in the near-infrared range, for potential use in bioimaging and therapy.
The largest share of the community's output is found in rhodium research, accounting for 9.8% of all rhodium research, and 3,018 papers here. It also represents 4.0% of palladium research (3,514 papers) and 2.5% of platinum research (3,342 papers).
The community comprises 30,924 papers, published primarily in the Journal of Catalysis, the Journal of the American Chemical Society, and Angewandte Chemie International Edition.
Recent work continues to focus on the synthesis of atomically precise gold and silver nanoclusters, including the development of gold quantum needles and near-infrared emitting clusters. Current research also examines the role of surface oxygen vacancies and hydrogen spillover in promoting hydrogenation efficiency, as well as the functionalization of nanoclusters for asymmetric catalysis.
