The lack of stability is a challenge for most heterogeneous catalysts. During operations, the
agglomeration of particles may block the active sites of the catalyst, which is believed to …

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 …

The ability to deposit intact polyatomic ions with well‐defined composition, charge state, and
kinetic energy onto surfaces makes preparative mass spectrometry, also called ion soft …

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 …

Carbon monoxide (CO) is one of the very poisonous gasses and major sources of CO
produced into the environment by the automobile vehicles exhaust. There are various types …

When small clusters are studied in chemical physics or physical chemistry, one perhaps
thinks of the fundamental aspects of cluster electronic structure, or precision spectroscopy in …

Abstract Au/TiO2, Pd/TiO2, Pt/TiO2 and Rh/TiO2 catalysts were synthesized by the
deposition–precipitation with urea (DPU) and sol–gel (SG) methods to elucidate the …

Oxidation of CO over size-selected Ptn clusters (n= 1, 2, 4, 7, 10, 14, 18) supported on
alumina thin films grown on Re (0001) was studied using temperature-programmed …

Small clusters have captured the imaginations of experimentalists and theorists alike for
decades. In addition to providing insight into the evolution of properties between the atomic …
