This thesis reports on the adsorption of two amino acids (AA) with different properties, Leucine and Glutamic acid, on the amorphous silica surface. It exemplifies a general approach to hybrid systems that combines experimental information and molecular modeling in order to characterize at the…, Cette thèse porte sur l'adsorption de deux acides aminés aux propriétés différentes, la leucine et l'acide glutamique, sur la surface de la silice amorphe. Une combinaison d'informations expérimentales et de modélisation moléculaire a été entreprise afin de caractériser au niveau…

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…

Surface Chirality of Gly-Pro Dipeptide Adsorbed on a Cu(110) Surface

Hervé Cruguel, Christophe Méthivier, Claire-Marie Pradier, Vincent Humblot

The adsorption of chiral Gly-Pro dipeptide on Cu(110) has been characterized by combining in situ polarization modulation infrared reflection absorption spectroscopy (PM-RAIRS) and X-ray photoelectron spectroscopy (XPS). The chemical state of the dipeptide, and its anchoring points and adsorption…

Catalytic properties of AgAlBEA and AgSiBEA zeolites in H2-promoted selective reduction of NO with ethanol

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Svitlana Orlyk, Stanislaw Dzwigaj

Physicochemical properties of AgAlBEA and AgSiBEA zeolites were investigated by IR spectroscopy with pyridine, H2-TPR, XPS and diffuse reflectance UV–vis spectroscopy. Their catalytic properties were studied in the process of selective reduction of NO with ethanol and in the presence of hydrogen in…

Identification of Surface Basic Sites and Acid–Base Pairs of Hydroxyapatite

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Sandra Casale, Cyril Thomas, Jun Kubo, Guylène Costentin

The Lewis and Brønsted basic properties of a stoichiometric hydroxyapatite (HAp) were investigated by infrared spectroscopy following the adsorption and desorption processes of a Lewis acidic molecule, CO2, and a Brønsted acidic molecule, C2H2. CO2 interacts with basic OH– and O2– of PO43– groups…
