Towards metal free supported quaternary ammonium halides catalysts for an optimized cycloaddition of CO 2 onto styrene oxide

Miguel Alonso de La Peña, Matthieu Balas, Julie Kong, Richard Villanneau, Lorraine Christ, A. Tuel, Franck Launay

The present work reports on a large selection of porous siliceous materials functionalised by quaternary ammonium salts (QAS) with various pores structures, possible doping with Zn2+, and different ammonium salt substituents as well as halide counter-ions. After characterization by TGA, N2…

On the promoting effect of Au on CO oxidation kinetics of Au-Pt bimetallic nanoparticles supported on SiO2: An electronic effect?

Rachel P. Doherty, Jean-Marc Krafft, Christophe Méthivier, Sandra Casale, Hynd Remita, Catherine Louis, Cyril Thomas

Bimetallic AuPt nanoparticles prepared by radiolysis with Au/Pt atomic ratios of 1.2 and 1.8 were deposited onto silica and calcined to remove the stabilizing polymers. During this sequence, they lose their core-shell structure and restructure as alloys. FTIR and XPS provide evidence for further…

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…

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…

Orientation of a Trametes versicolor laccase on amorphous carbon nitride coated graphite electrodes for improved electroreduction of dioxygen to water

Achraf Blout, Florence Billon, Christophe Calers, Christophe Méthivier, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Amorphous carbon nitride (a-CNx) thin films were used for the first time as electrode materials in the elaboration of biofuel cell cathodes as a consequence of i) the natural presence of amine type functional groups and ii) the ease to generate carboxylic acid groups on their surface with the help…

Development of novel anti-Kv 11.1 antibody-conjugated PEG-TiO2 nanoparticles for targeting pancreatic ductal adenocarcinoma cells

Angelica Sette, Jolanda Spadavecchia, Jessem Landoulsi, Sandra Casale, Bernard Haye, Olivia Crociani, Annarosa Arcangeli

Titanium dioxide (TiO2) has been widely used in many nanotechnology areas including nanomedicine, where it could be proposed for the photodynamic and sonodynamic cancer therapies. However, TiO2 nanoformulations have been shown to be toxic for living cells. In this article, we report the development…
