Nanostructured catalysts incorporating supported metal atoms or small clusters of defined
size and chemical composition attract considerable attention because of their potential to …

Metal nanoclusters (NCs), which are composed of about 250 or fewer metal atoms, possess
great potential as novel functional materials. Fundamental research on metal NCs gradually …

X-ray photoelectron spectroscopy (XPS) has achieved maturity as an analytical technique in
that it is a ubiquitous tool in the materials community, however as made apparent by recent …

Small clusters secured at a given size, for example, via deposition on surfaces of
semiconductors, can be remarkable catalysts. In the so-called “non-scalable” regime, where …

Size-selected Cu n catalysts (n= 3, 4, 20) were synthesized on Al2O3 thin films using mass-
selected cluster deposition. A systematic study of size and support effects was carried out for …

Catalytic dehydrogenation of ethylene on size-selected Pt n (n= 4, 7, 8) clusters deposited
on the surface of Al2O3 was studied experimentally and theoretically. Clusters were mass …

Size-selected supported clusters of transition metals can be remarkable and highly tunable
catalysts. A particular example is Pt clusters deposited on alumina, which have been shown …

Conspectus Mass-selected Pt n+ ion deposition in ultrahigh vacuum (UHV) was used to
prepare a series of size-selected electrodes with Pt n (n≤ 14) clusters supported on either …

Metal nanoclusters (NCs) are one of the leading targets in research of nanoscale materials,
and elucidation of their properties (science) and development of control techniques …

X-ray absorption near-edge structure (XANES) is commonly used to probe the oxidation
state of metal-containing nanomaterials; however, as the particle size in the material drops …
