Monitoring of the Plasmon Resonance of Gold Nanoparticles in Au/TiO2 Catalyst under Oxidative and Reducing Atmospheres

Yves Borensztein, Laurent Delannoy, Anis Djedidi, Ruben G. Barrera, Catherine Louis

Diffuse optical reflectance of Au/TiO2 powder catalysts, prepared by the deposition-precipitation method, is measured in the UV-visible range in controlled atmosphere. An intense optical absorption observed around 550 nm is interpreted by the excitation of plasmon resonances in the 4 nm gold…

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…

In situ surface imaging: High temperature environmental SEM study of the surface changes during heat treatment of an Al Si coated boron steel

M. Barreau, C. Méthivier, T. Sturel, C. Allely, P. Drillet, S. Cremel, R. Grigorieva, B. Nabi, Renaud Podor, J. Lautru, V. Humblot, J. Landoulsi, X. Carrier

Al-Si coated boron steels have been of interest for many years because of their superior mechanical properties and their excellent oxidation resistance. These high strength steels are particularly used in hot stamping processes during which the Al-Si coating undergoes multiple microstructural…

A New Nanocomposite: L-DOPA/Laponite

Maguy Jaber, Jean-Francois Lambert

A simple procedure is reported to obtain original nanocomposite materials combining the smectite Laponite and melanin-like polymers. Aq. polymn. of L-DOPA is considerably accelerated in the presence of suspended Laponite particles, and its mechanism is significantly modified with respect to…

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…

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…

No particle size effects in the electrochemical conversion of Co2 to formate on Sn electrodes

Carlos M Sánchez-Sánchez, A. Del Castillo, Manuel Alvarez-Guerra, Juliette Blanchard, A. Irabien

Recycling of CO2 emissions by direct electrocatalytic reduction of CO2 has been pointed out as a feasible method for CO2 conversion into useful chemical products and fuels. In particular, formic acid (HCOOH) represents one of the most interesting products obtained, since HCOOH is widely used in…
