The adsorption of ethylene on Au/Pd(111) alloy surfaces
The adsorption of ethylene on gold–palladium alloys formed on a Pd(111) surface is investigated using a combination of temperature-programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS). Various alloy compositions are obtained by depositing four monolayers of gold on a clean Pd(111) surface and annealing to various temperatures. For gold coverages greater than 0.7, ...
متن کاملHydrogen Adsorption and Absorption with Pd−Au Bimetallic Surfaces
Pd−Au bimetallic catalysts have shown promising performance in numerous reactions that involve hydrogen. Fundamental studies of hydrogen interactions with Pd−Au surfaces could provide useful insights into the reaction mechanisms over Pd−Au catalysts, which may, in turn, guide future catalyst design. In this study, the interactions of hydrogen (i.e., adsorption, absorption, diffusion, and desorp...
متن کاملElectrochemical Characterization of Protein Adsorption onto YNGRT-Au and VLGXE-Au Surfaces
The adsorption of the proteins CD13, mucin and bovine serum albumin on VLGXE-Au and YNGRT-Au interfaces was monitored by electrochemical impedance spectroscopy in the presence of [Fe(CN)6](3-/4-). The hydrophobicity of the Au surface was tailored using specific peptides, blocking agents and diluents. The combination of blocking agents (ethanolamine or n-butylamine) and diluents (hexanethiol or ...
متن کاملTheoretical study of Di-Amino-Triazine adsorption on Cu(110) and Au(111) surfaces
The diffusion of adatoms or molecules on metal surfaces is the lifeblood of many phenomena as growth. Various microscopic experiences realized by STM (Scanning Tunneling Microscopy) or by AFM (Atomic Force Microscopy) techniques at CEMES center show that the determination of some variables is very necessary to overcome many experimental difficulties. In this paper, MM4 (Molecular Mechanics (200...
متن کاملAdsorption of Dichlorobenzene on Au and Pt Stepped Surfaces Using van der Waals Density Functional Theory
The adsorption of dichlorobenzene on flat (111) and stepped (332) Au and Pt surfaces was studied using density functional theory with both a conventional generalized gradient approximation (GGA) and a fully nonlocal van der Waals density functional (vdWDF). The equilibrium geometries and adsorption energies were computed for several different adsorption configurations. The two functionals yield...
