In situ electron energy loss spectroscopy studies of gas-dependent metal-support interactions in Cu/ZnO catalysts
Article Abstract:
The insight into the Cu-ZnO interaction under different gas conditions by combining the in situ transmission electron microscopy (TEM) results with in situ electron energy loss spectroscopy (EELS) measurements is investigated. Variations in the energy loss near edge structure (ELNES) intensity at the Cu L3 edge are interpreted as a tensile strain in the Cu nanoclusters induced by the ZnO support and a Cu-Zn alloy formation at the Cu/ZnO interface induced by increasing the reduction potential in the gas phase.

Structure and reactivity of Ni-Au nanoparticle catalysts
Article Abstract:
The design of a Ni-Au nanoparticle catalyst system, which is based on the detailed experimental and theoretical understanding of the alloying and the chemical reaction processes on single-crystal surfaces, is discussed. The alloy formation and structure of Ni-Au catalysts supported on SiO2 and on MgAl2O4 are simulated by Monte Carlo schemes as well as experimentally studied by a combination of in situ X-ray absorption fine structure, transmission electron microscopy, and in situ X-ray powder diffraction.

Solvent density effects on the solvation behavior and configurational structure of bare and passivated 38-atom gold nanoparticle in supercritical ethane
Article Abstract:
The effects of the changes in the density of the solvent on the solvation behavior of the bare and passivated gold particle in the supercritical regime is elucidated. The solvating molecules are strongly bound to the bare particle, forming a well-defined solvation layer that is composed of two distinct regions, an inner region and an outer region.
