AuS and SH Bond Formation/Breaking during the Formation of Alkanethiol SAMs on Au(111): A Theoretical Study

Frederik Tielens, Elizabeth Santos

The bonding of propanethiol mols. on a Au(111) surface is studied using period DFT calcns. within the framework of the model for chem. bond breaking that was recently proposed. The S-H bond breaking and the Au-S bond formation are analyzed through the evolution of the d. of states. The energetics…

The Formation of Gold Clusters Supported on Mesoporous Silica Material Surfaces: A Molecular Picture

A. Wojtaszek, I. Sobczak, M. Ziolek, Frederik Tielens

The interaction of gold particles with a silica surface is investigated using a combination of theor. and exptl. techniques. It is found that the physisorption strength of gold on silica decreases with increasing chloride concn. at the surface, with increasing cluster size, and with decreasing…

Experimental evidence of NO SCR mechanism in the presence of the BEA zeolite with framework and extra-framework cobalt species

Paweł Boroń, Lucjan Chmielarz, Barbara Gil, Bartosz Marszałek, Stanislaw Dzwigaj

Temperature-programmed desorption (TPD), temperature-programmed surface reaction (TPSR) and stop flow-TPD techniques as well as FT-IR spectroscopy of pre-adsorbed NH3 and NO are applied to characterize active sites present in Co-containing BEA zeolites. Cobalt is introduced into BEA zeolite by…

Chiral self-assemblies of amino-acid molecules: D- and L-methionine on Au(111) surface

Ahmed Naitabdi, Vincent Humblot

Spontaneous self-assembly into chiral well-ordered two-dimensional molecular film at room temperature has been evidenced using the scanning tunneling microscopy for the growth of two enantiomerically pure L- and D-methionine on Au(111) surface. From the x-ray photoelectron spectroscopy measurements…

Adsorption of chiral molecules in oxide-supported heterogeneous catalysts : a model approach, Adsorption de molécules chirales sur catalyseurs hétérogènes supportés sur oxyde : une approche modèle

Elisa Meriggio

Enantioselective heterogeneous catalysis is a method of choice for the synthesis of enantiopure chiral products. One current approach involves the modification of a metal surface by a chiral modifier. Despite its great potential, only a small number of successful systems have been developed so far…, La catalyse asymétrique hétérogène est une méthode de choix pour la synthèse de composés chiraux énantiopurs. Une approche courante implique la modification d'une surface métallique par un inducteur chiral. Malgré son potentiel, seul un petit nombre de systèmes ont été mis au point jusqu'…
