چکیده

The connection between local structure and the grain size distribution in nanophase palladium is studied by XAFS and x-ray diffraction (XRD). We show that there is a reduced average coordination number in all samples; this reduction is compatible with a size effect, cmtradicting previous XAFS measurements. Both a f i t shell analysis and a full analysis up to the 8th coordination shell, including multiple-scattering, are reported.

Atomic force and scanning tunneling microscopy analysis of palladium and silver nanophase materials

Atomic force and scanning tunneling microscopy images of nanophase palladium and silver materials taken on various length scales are presented. The samples show a conformational packing of individual nanometer-sized clusters. In the case of silver, islands of clusters are observed on micrometer length scales. The islands are very tlat and separated by deep crevices. The grains (clusters) within...

Palladium nanoparticles synthesis using polymeric matrix: poly(ethyleneglycol) molecular weight and palladium concentration effects

Due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple and low cost method is very important. In this work, Pd nanoparticles were synthesized with narrow size distribution by loading metal salt (Pd(OAc)2 ) into the polymeric matrix (PEG) as reducing agent and stabilizer. Also, the effect of metal salt concentration and PEG molecular weight on the con...

Calculation for Energy of (111) Surfaces of Palladium in Tight Binding Model

In this work calculation of energetics of transition metal surfaces is presented. The tight-binding model is employed in order to calculate the energetics. The tight-binding basis set is limited to d orbitals which are valid for elements at the end of transition metals series. In our analysis we concentrated on electronic effects at temperature T=0 K, this means that no entropic term will be pr...

بررسی قابلیت جذب هیدروژن در ماده مرکب نانو‌ساختار SBA-16-Pd

The purpose of this work was to study the hydrogen adsorption on the surface of mesoporous materials based on silica (SBA-16) modified with palladium via temperature. Since mesoporous silica materials have a high specific surface area, and the ordered mesoporous size of 2-10nm, they are suitable for adsorption and storage of hydrogen. SBA-16 is suitable for this purpose due to its cubic crystal...
