A comparative study of the catalysis of peptide bonds formation by oxide surfaces

Jean-Francois Lambert, Maguy Jaber, Thomas Georgelin, Lorenzo Stievano

It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which…

Hydrodenitrogenation of indole over Mo2C catalyst: Insights into mechanistic events through DFT modeling

Witold Piskorz, Grzegorz Adamski, Andrzej Kotarba, Zbigniew Sojka, Céline Sayag, G. Djéga-Mariadassou

The molecular reaction mechanism of hydrodenitrogenation of indole was studied using density-functional theory calculations of the adsorbed o-ethylaniline surrounded by mobile hydrogen atoms. It was found that the hydrogenation of o-ethylaniline occurs through two steps: consisting in…

Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…

Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…

Photoelectrochemical properties of nanocrystalline ZnS discrete versus continuous coating of ZnO nanorods prepared by electrodeposition

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, A. Souissi, L. Mouton, P. Beaunier, S. Nowak, F. Mammeri, R. Chtourou, S. Ammar

We developed nanostructured photoanodes for photoelectrochemical (PEC) water splitting and hydrogen generation. They are based on ZnO nanorods electrodeposited on conductive ITO glass on which ZnO@ZnS heterojunctions were formed using two different approaches. In the first case, the ZnO nanorods…
