In recent years, the field of catalysis has experienced an astonishing transformation, driven
in part by more demanding environmental standards and critical societal and industrial …

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 …

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 …

Control of heterogeneous catalytic sites through their surrounding chemical environment at
an atomic level is crucial to catalyst design. We synthesize Pd nanoclusters (NCs) in an …

Size-selected clusters containing a handful of atoms may possess noble catalytic properties
different from nano-sized or bulk catalysts. Size-and composition-selected clusters can also …

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 …

The review addresses the development of the methodology of single-atom catalysts ranging
from single-site to single-atom alloy systems. The preparation and characterization of single …

We present a combined experimental/theoretical study of Pt n/SiO2 and Pt n Sn x/SiO2 (n=
4, 7) model catalysts for the endothermic dehydrogenation of hydrocarbons, using the …

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 …

Deposition of size-selected Pt n clusters on indium tin oxide (ITO) films in ultrahigh vacuum
was used to create electrodes with catalytic sites of controlled size. We report a study of the …
