Quantitative relationship between the nature of surface species and the catalytic activity of tungsten oxides supported on crystallized titania

Thomas Onfroy, Vanessa Lebarbier, Guillaume Clet, Marwan Houalla

A series of WOx/TiO2 catalysts contg. between 0.6 and 3.4 W at./nm2 was prepd. by pore vol. impregnation using ammonium metatungstate soln. on crystd. TiO2. Characterization of the solids by X-ray diffraction and Raman and IR spectroscopy indicated that the W phase was present essentially as a…

Catalytic Aspects of Light-Induced Hydrogen Generation in Water with TiO2 and Other Photocatalysts: A Simple and Practical Way Towards a Normalization?

Thomas Maschmeyer, Michel Che

Evaluation is discussed of performance of solid photocatalysts for H2 generation from H2O so that they can be compared in a simple way whether sacrificial soln. is used or not. The addnl. chem. potential present in a sacrificial soln. will be the same regardless of the catalyst system used, so…

Tunable plasmonic substrates for LSPR biosensing, Substrats plasmoniques accordables pour la biodétection LSPR

Daoming Sun

This PhD project was organized into three primary phases: the synthesis and optimization of hollow-structured plasmonic nanoparticles, the fabrication and characterization of glass-based plasmonic sensors, and the application of nanostructured plasmonic platforms for biosensing. First, we refined…, Dans ce travail, nous avons affiné et optimisé un protocole de synthèse bien établi pour les nanocoques d'or, en améliorant leurs propriétés structurelles par le biais de travaux expérimentaux et de simulations afin d'améliorer leurs performances en matière de détection réfractométrique.…

Covalent Transition Metal Borosilicides: Reaction Pathways in Molten Salts for Water Oxidation Electrocatalysis

Daniel Janisch, Fernando Igoa Saldaña, Edouard de Rolland Dalon, Carlos V. M. Inocêncio, Yang Song, Pierre-Olivier Autran, Antoine Miche, Sandra Casale, David Portehault

The properties of transition metal borides and silicides are intimately linked to the covalent character of the chemical bonds within their crystal structures. Bringing boron and silicon together within metal borosilicides can then engender different competing covalent networks and complex charge…

Functionalisation of gold surfaces with thiolate SAMs: Topography/bioactivity relationship – A combined FT-RAIRS, AFM and QCM investigation

E. Briand, C. Gu, S. Boujday, M. Salmain, Jean-Marie Herry, C.M. Pradier

Immobilisation of rabbit immunoglobulin G (rIgG) was performed by affinity binding to protein A (PrA) covalently bound to threedifferent thiolate self-assembled monolayers (SAMs), (i) a mixed SAM of mercaptoundecanoic acid (MUA) and mercaptohexanol(C6OH) at a molar ratio of 1–3, (ii) a pure SAM of…

Thermal Behavior of d -Ribose Adsorbed on Silica: Effect of Inorganic Salt Coadsorption and Significance for Prebiotic Chemistry

Mariame Akouche, Maguy Jaber, Emilie-Laure Zins, Marie-Christine Maurel, Jean-Francois Lambert, Thomas Georgelin

Understanding ribose reactivity is a crucial step in the “RNA world” scenario because this molecule is a component of all extant nucleotides that make up RNA. In solution, ribose is unstable and susceptible to thermal destruction. We examined how ribose behaves upon thermal activation when adsorbed…

Magnetic Traits in CoO‐Core@CoFe 2 O 4 ‐shell Like Nanoparticles

Nancy Flores-Martinez, Margot Roemer, Sarra Gam-Derouich, Patricia Beaunier, David Habrovsky, Souad Ammar

Antiferromagnetic (AF) CoO pseudo-single crystals 125±20 nm in diameter were prepared by forced hydrolysis in polyol and used as seeds to grow a poly- and nano-crystalline (5 nm in diameter) ferrimagnetic (F) CoFe2O4 shell. Transmission electron microscopy (TEM) showed a certain epitaxy between the…

Controlled preparation of CoPdSiBEA zeolite catalysts for selective catalytic reduction of NO with methane and their characterisation by XRD, DR UV-vis, TPR, XPS

Ana Rodrigues, Patrick da Costa, C. Methivier, S. Dzwigaj

The Pd0.15SiBEA and CoxPd0.15SiBEA zeolites (where x= 1.0 and 3.0 wt.% Co) are prepared by a two-step postsynthesis method which allows to control the introduction of palladium and cobalt into zeolite and thus to obtain catalysts with specific bimetallic Pd and Co sites. The effect of Co content on…
