Mesoporous alumina of controlled pore size obtained by surface alumination of pure silica SBA 15

Emmanuel de La Rochefoucauld, Xavier Carrier, Jean-Marc Krafft, Juliette Blanchard

Silica-alumina oxide supports were synthesized by surface alumination of mesoporous silica SBA-15 with Al isopropoxide in organic solvents. These materials were characterised by N2 adsorption-desorption isotherms, XRD, 27Al NMR and cumene cracking. The chemical nature of the surface was probed by…

Surface-dependent sulfidation and orientation of MoS 2 slabs on alumina-supported model HDS catalysts

Cédric Bara, Anne-Félicie Lamic-Humblot, Emiliano Fonda, Anne-Sophie Gay, Anne-Lise Taleb, Elodie D Devers, Mathieu D Digne, Gerhard D Pirngruber, Xavier Carrier

The constant improvement of hydrotreating (HDT) catalysts, driven by industrial and environmental needs, requires a better understanding of the interactions between the oxide support (mostly alumina) and the MoS2 active phase. Hence, this work addresses the support-dependent genesis of MoS2 on four…

Direct AFM force mapping of surface nanoscale organization and protein adsorption on an aluminum substrate

Jessem Landoulsi, V. Dupres

We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity,…

End-Cretaceous akaganéite as a mineral marker of Deccan volcanism in the sedimentary record

Eric Font, Julie Carlut, Céline Remazeilles, Tamsin A Mather, Anne Nédélec, Jose Mirao, Sandra Casale

An enigmatic chloride-rich iron (oxyhydr)oxide has been recently identified together with mercury anomalies in End-Cretaceous marine sediments coeval with the Deccan Traps eruptions. The mineral was observed in Bidart (France) and Gubbio (Italy), suggesting a widespread phenomenon. However, the…

Influence of synthesis parameters of SBA-15 supported palladium catalysts for methane combustion and simultaneous NOx reduction

Maya Boutros, María Elena Gálvez, Thomas Onfroy, Patrick da Costa

Several synthesis routes were followed to prepare ordered mesoporous silica, SBA-15, and alumino-silica, Al–SBA-15, supported palladium catalysts. Synthesis method as well as the nature of precursor used in the preparation of these catalysts strongly determined their physico-chemical features which…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…
