Homogeneous Supported Monolayer from Microbial Glycolipid Biosurfactant

Niki Baccile, Anyssa Derj, Cedric Boissiere, Vincent Humblot, Ariane Deniset-Besseau

The development of supported glycosylated lipid layers is an important trend in the field of glyconanomaterials for their interest in understanding sugar-sugar and protein-sugar interactions, these being at the core of cellular, bacterial or viral adhesion. The conventional self-assembled monolayer…

Molecular Understanding of the Bulk Composition of Crystalline Nonstoichiometric Hydroxyapatites: Application to the Rationalization of Structure-Reactivity Relationships

Manel Ben Osman, Jean Marc Krafft, Yannick Millot, Frederic Averseng, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Crystalline hydroxyapatite samples (HAps) have been prepared by using the co-precipitation method under various pH conditions, leading to nonstoichiometric solids (1.65 < Ca/P < 1.77). The aim of this study was to rationalize the sensitivity of the catalytic activity of HAps to their bulk…

Rational design of a CO2-resistant toluene hydrogenation catalyst based on FT-IR spectroscopy studies

Julien Scalbert, Cécile Daniel, Yves Schuurman, Cyril Thomas, Frédéric C. Meunier

Rhodium highly dispersed on alumina becomes partly poisoned by strongly bound CO when used for toluene hydrogenation at 348 K in the presence of CO2. Operando FT-IR analysis enabled to observed CO(ads) build up over the sample, while no CO(gas) could be measured in the reactor effluent. Analyses…

Copper incorporated mesoporous materials: synthesis, characterization and catalytic activity in benzaldehyde reduction

O. Zekri, A. Saadi, F. Launay, C. Calers, C. Rabia

Copper substituted mesoporous silica materials (Cu–HMS-n), with a variety of Si/Cu atomic ratios (n) ranging from 50 to 100, were synthesized by the one-pot sol–gel method using dodecylamine as template. These materials were characterized by X-ray diffraction, N2 adsorption-desorption, transmission…

Dealuminated Beta Zeolite Modified by Alkaline Earth Metals

Karolina Chalupka, Renata Sadek, Laetitia Valentin, Yannick Millot, Christophe Calers, Magdalena Nowosielska, Jacek Rynkowski, Stanislaw Dzwigaj

Alkaline Earth metals (Mg, Sr, and Ca) were incorporated into the dealuminated mesoporous beta zeolite (DeAlBeta) by the two-step postsynthesis method. Physicochemical properties of both unmodified and alkaline Earth metal-modified DeAlBeta zeolite were characterized by XRD, DR UV-vis, FTIR, TPD of…

Particle Size Effects in the Selective Hydrogenation of Alkadienes over Supported Cu Nanoparticles

Giorgio Totarella, Jan Willem de Rijk, Laurent Delannoy, Petra de Jongh

Copper is considered an excellent alternative to noble-metal selective hydrogenation catalysts. Herein, we systematically studied the effect of Cu nanoparticle size (2-10 nm) in the selective hydrogenation of 1,3-butadiene in excess of propene. The catalysts exhibited particle size-dependent…
