Chiral Recognition of l-Gramicidine on Chiraly Methionine-Modified Au(111)

Vincent Humblot, Claire-Marie Pradier

A chiral pentadecapeptide, l-gramicidine, has been shown to undergo specific adsorption onto gold surfaces modified by chiral amino acids, d- and l-methionine, upon adsorption in the liquid phase. There is a chiral recognition only between the slightly anionic l-peptide and the l-modified surface…

Investigation of co-hosted basic and metal nanoparticles in Pt/Cs-BEA zeolites

C. Bisio, Katia Fajerwerg, G. Martra, P. Massiani

Various acido-basic BEA zeolites having different Cs contents and containing supported Pt particles were prepared using two acidic parent BEA supports with same framework Al content but with strongly different morphology of the zeolite crystallites. In spite of highly different exchange capacities…

Monitoring by in situ neutron diffraction of simultaneous dehydration and Ni2+ mobility in partially exchanged NaY zeolites

Florence Porcher, Jean-Louis Paillaud, Lucia Gaberova, Gilles André, Sandra Casale, Pascale Massiani

Powder neutron diffraction is used to follow structural changes occurring during heat and vacuum assisted dehydration of 3 wt% nickel exchanged NaY. The structures determined from Rietveld refinement confirm the nickel ion displacement from the supercages and sodalite cages towards hexagonal prisms…

On the radical cracking of n-propylbenzene to ethylbenzene or toluene over Sn/Al2O3-Cl catalysts under reforming conditions

S Toppi, C Thomas, C Sayag, D Brodzki, Katia Fajerwerg, F Lepeltier, C Travers, G Djegamariadassou

Two series of chlorided-alumina-supported Sn catalysts were synthesized with different precursors, SnCl2 or SnBu4, and with various contents of Sn. The acidity of the catalysts including 0.2 wt% Sn was characterized by FTIR adsorption–desorption of 2,6-dimethylpyridine (Brønsted acidity) and…

Zeolite and Silica-based CO2 Adsorbents

Guillaume Laugel, Rogeria Bingre, Benoît Louis

The ever-increasing CO2 concentration in the atmosphere leading to global warming is one of the main problems that mankind has to face in the 21st century. To avoid the fact that sooner or later humanity will directly start to suffer from it, there is an urgent need to reduce the CO2 level by…

Adsorption of Amino Acids and Peptides on Metal and Oxide Surfaces in Water Environment: A Synthetic and Prospective Review

D. Costa, L. Savio, Claire-Marie Pradier

Amino acids and peptides are often used as “model” segments of proteins for studying their behavior in various types of environments, and/or elaborating functional surfaces. Indeed, though the protein behavior is much more complex than that of their isolated segments, knowledge of the binding mode…

Novel non-noble bimetallic Cu-Zn/TiO 2 catalysts for selective hydrogenation of butadiene

Zhao Wang, Guillaume Wang, Catherine Louis, Laurent Delannoy

Oxide-supported copper catalysts are active for the selective hydrogenation of polyunsaturated hydrocarbons with high selectivity to alkenes formation, but a low catalytic stability limits its application. The goal of the work was to investigate whether alloying Cu with Zn will improve catalyst…
