Mesoporous silica supported amine and amine-copper complex for CO2 adsorption: Detailed reaction mechanism of hydrophilic character and CO2 retention

Bouhadjar Boukoussa, Aboubakr Hakiki, Nabil Bouazizi, Ana-Paola Beltrao-Nunes, Franck Launay, Alain Pailleret, Françoise Pillier, Abdelkader Bengueddach, Rachida Hamacha, Abdelkrim Azzouz

Mesoporous silica SBA-15 was functionalized with various amines and then doped with copper II cation (Cu2+). The modified materials were tested for the retention of CO2 at room temperature using temperature-programmed desorption (CO2-TPD). Several parameters affecting the CO2 retention capacity (…

Influence of Coadsorbed Water and Alcohol Molecules on Isopropyl Alcohol Dehydration on γ-Alumina: Multiscale Modeling of Experimental Kinetic Profiles

Kim Larmier, Andre Nicolle, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Successfully modeling the behavior of catalytic systems at different scales is a matter of importance not only for a fundamental understanding but also for a more rational design of catalysts and a more precise definition of the kinetic laws used as inputs in chemical engineering. We have developed…

One-Pot Radiolytic Synthesis of Gold Nanorods and Their Optical Properties

Wafa Abidi, P. R. Selvakannan, Yanick Guillet, Isabelle Lampre, Patricia Beaunier, Brigitte Pansu, Bruno Palpant, Hynd Remita

A novel one-pot synthesis method to prepare gold nanorods of different aspect ratios using radiolysis is presented. The gold nanorods are synthesized by radiolytic reduction of Au-III complexes in a micellar solution formed by a mixture of cationic surfactants (cetyltrimethylammonium bromide and…

Phosphate Boosts Nonhydroxyl Radical Species Production upon Air Oxidation of Magnetite and Iron Sulfides at Neutral pH

Guillaume Morin, Frédéric Averseng, Xavier Carrier, Pierre Le Pape, Yishan Du, Yusheng Honge, Elora Bourbon, Giuseppe Sportelli, Tiago A da Silva, Alberto Mezzetti, Camille Baya, Thierry Allard, Jessica Brest, Maryse Rouelle

Heterogeneous Fenton-like reactions using O2 as sole oxidant are gaining interest for designing organic contaminant degradation in soils and groundwaters, since they may provide alternatives to current processes involving strong oxidants. Indeed, several Fe(II)-bearing oxide and sulfide mineral…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…
