Microwave bentonite silylation for dye removal: Influence of the solvent

Líbia N.F. Queiroga, Mariana B.B. Pereira, Lucinaldo Silva, Edson Silva Filho, Ieda M.G. Santos, Maria Fonseca, Thomas Georgelin, Maguy Jaber

A series of bentonite silylated samples was prepared with aminopropyltrimethoxy silane over a short period of time (5 min), at 50 °C, using microwave irradiation. The influence of polar and non-polar solvents was investigated. The pristine and modified solids were characterized by structural,…

Immobilization of atrazine on gold, a first step towards the elaboration of an indirect immunosensor, characterised by XPS and FT-IRRAS

Michèle Salmain, Natahlie Fischer-Durand, Céline Roche, Claire-Marie Pradier

As part of our long-term goal to design a novel type of immunosensor based on IR transduction, we devised two strategies to immobilize derivatives of the herbicide atrazine on the surface of planar gold substrates. Both strategies take advantage of the well-known formation of self-assembled…

Etude des paramètres influençant la réactivité de bases inorganiques faibles : application à la catalyse hétérogène de transestérification, Study of the parameters governing the reactivity of weak inorganic bases : towards the transesterification reaction

Damien Cornu

Les enjeux actuels pour la valorisation de dérivés de la biomasse donnent à la catalyse hétérogène basique un intérêt nouveau. Dans la mesure où des relations complexes peuvent exister entre la performance d'un catalyseur hétérogène basique et sa force déprotonante, une étude des critères qui…, The current challenges for the valorization of biomass derived products contribute to a growing interest for basic heterogeneous catalysis. Because of the complex connection between the catalytic performance of a basic heterogeneous catalyst and its deprotonating ability, a study of the parameters…

“Nanocasting”: using SBA-15 silicas as hard templates to obtain monodispersed superparamagnetic gamma-Fe2O3 nanoparticles

Anne Davidson, Emilie Delahaye, Virginie Escax, Nissrine El Hassan, Renata Aquino, Vincent Dupuis, Regine Perzynski, Yuri Raikher

This work describes the use of mesoporous SBA-15 silicas as hard templates, for the size-controlled synthesis of oxides nanoparticles, the pores acting as nanoscale reactors. This fundamental work is mainly aimed at understanding unresolved issues concerning the occurrence and size dependence of…

Size-induced structural modifications affecting Co3O4 nanoparticles patterned in SBA-15 silicas

Anne Davidson, Irene Lopez, Nissrine El Hassan, Hadjira Guerba, Gilles Wallez

The structure of Co3O4 nanoparticles patterned in SBA-15 silicas is studied. With pore size of 7.3 nm, bundles of oriented particles, with (400) plane parallel to the hexagonal axis, is revealed by HR-TEM. With decreasing pore sizes, structural modifications, suggested by HR-TEM are confirmed by…

Reshaping Dynamics of Gold Nanoparticles under H2 and O2 at Atmospheric Pressure

Adrian Chmielewski, Jun Meng, Beien Zhu, Yi Gao, Hazar Guesmi, Hélène Prunier, Damien Alloyeau, Guillaume Wang, Catherine Louis, Laurent Delannoy, Pavel Afanasiev, Christian Ricolleau, Jaysen Nelayah

Despite intensive research efforts, the nature of the active sites for O2 and H2 adsorption/dissociation by supported gold nanoparticles (NPs) is still an unresolved issue in heterogeneous catalysis. This stems from the absence of a clear picture of the structural evolution of Au NPs at near…

Factors impacting the aggregation/agglomeration and photocatalytic activity of highly crystalline spheroid- and rod-shaped TiO 2 nanoparticles in aqueous solutions

Thomas Degabriel, Elodie Colaço, Rute F Domingos, Karim El Kirat, Dalil Brouri, Sandra Casale, Jessem Landoulsi, Jolanda Spadavecchia

We investigate the characteristics, fate and photocatalytic activity of spheroid- and rod-shaped TiO2 nano-crystals in aqueous solutions to better understand their behaviour in media of biological and environmental interest. For this purpose, the potential of a solvothermal method in synthesizing…

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…
