Investigation of the role of stabilizingagentmolecules in the heterogeneousnucleation of rhodium(0) nanoparticles onto Al-SBA-15 supports

Rita Sassine, E. Bilé-Guyonnet, Thomas Onfroy, Audrey Denicourt-Nowicki, Alain Roucoux, Franck Launay

Interactions of stabilizingagentmolecules (HEA16Cl) with Rh(0) particles and mesoporous aluminosilic supports were studied in rhodium(0) catalysts obtained by heterogeneousnucleation. HEA16Cl/Rh(0) proximity was indirectly demonstrated by monitoring the CO coverage of metal surface using FTIR…

BSA and lysozyme adsorption on homoionic montmorillonite: Influence of the interlayer cation

Mathilde Lepoitevin, Maguy Jaber, Régis Guégan, Jean-Marc Janot, Philippe Dejardin, Francois Henn, Sébastien Balme

This study aims to investigate the influence of interlayer cation alkali metal series (Li+, Na+, K+, Rb+, Cs+) and alkali earth metal (Mg2 +, Ca2 +, Ba2 +) on adsorption of model proteins (lysozyme and bovine serum albumin). The localizations of both proteins and their conformational modifications…

Elucidation of the low coverage chiral adsorption assembly of L-lysine on Cu(110) surface: A theoretical study

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier

The adsorption of L-lysine on Cu(110) surface was studied using periodic DFT. The geometry is discussed in terms of the molecular electrostatic interactions, and electronic properties such as DOS. An STM image was simulated and compared with our recently obtained experimental results. Compelling…

On the detrimental effect of tungstates on the n-C10-SCR of NOx on Ag/g-Al2O3

Juliette Blanchard, Rachel P. Doherty, Hiu Ying Law, Christophe Méthivier, Cyril Thomas

The influence of the addition of W to Al2O3, promoted or not by Ag, on the n-C10 SCR of NOx was investigated. It was shown that the addition of W was detrimental to the n-C10 SCR reaction. Based on the NOx- TPD, the XPS and the n-C10 SCR measurements, it was concluded that the loss of activity…

Gold Grafted to Mesoporous Silica Surfaces, a Molecular Picture

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

The adsorption of HAuCl(4), the typical precursor for gold grafting on metal oxide surfaces, is investigated on amorphous silica support. The adsorption of the precursor is investigated as a function of its chlorinated form, depending on the pH, using periodic DFT. The results are supported with…

Mn-analcime: Synthesis, characterization and application to cyclohexene oxidation

Amal Bejar, Semy Ben Chaabene, Maguy Jaber, Jean-François Lambert, Latifa Bergaoui

The hydrothermal synthesis of Mn-analcime was performed by mixing manganese(II) carbonate, silicic acid and aluminum nitrate in a basic medium in the 120–175 °C temperature range for 6–72 h. Different Mn/Al ratios were used. The obtained samples were characterized by powder XRD, N2 physical…
