Characterization of Solid Materials and Heterogeneous Catalysts: From Structure to Surface Reactivity, Volume 1&2

Che Michel, Védrine Jacques C.

This two-volume book provides an overview of physical techniques used to characterize the structure of solid materials, on the one hand, and to investigate the reactivity of their surface, on the other. Therefore this book is a must-have for anyone working in fields related to surface reactivity.…

Preparation of Highly Anisotropic Cobalt Ferrite/Silica Microellipsoids Using an External Magnetic Field

Sébastien Abramson, Vincent Dupuis, Sophie Neveu, Patricia Beaunier, David Montero

Magnetic cobalt ferrite/silica microparticles having both an original morphology and an anisotropic nanostructure are synthesized through the use of an external magnetic field and nanoparticles characterized by a high magnetic anisotropy. The association of these two factors implies that the ESE…

Exploring the reactivity of intraframework vanadium, niobium and tantalum sites in zeolitic materials using the molecular electrostatic potential

Frederik Tielens

The acid-base properties of group 5 zeolitic structures are discussed using the molecular electrostatic potential. The results point out that vanadium doped zeolites are less appropriate for electrophilic reactions, yielding minor basic character when they are compared with Nb or Ta doped zeolites.…

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…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…

Engineering of Antimicrobial Surfaces by Using Temporin Analogs to Tune the Biocidal/antiadhesive Effect

Pierre-Carl Oger, Christophe Piesse, Ali Ladram, Vincent Humblot

Proliferation of resistant bacteria on biomaterials is a major problem leading to nosocomial infections. Due to their broad-spectrum activity and their ability to disrupt bacterial membranes through a rapid membranolytic mechanism, antimicrobial peptides (AMPs) are less susceptible to the…

Characterisation and Reactivity of Oxygen Species at the Surface of Metal Oxides

M. Anpo, Guylène Costentin, E. Giamello, H. Lauron-Pernot, Z. Sojka

Surface reactive oxygen species play a fundamental role in selective oxidation and combustion reactions catalyzed by metal oxides. Unravelling the nature of these transient species, and understanding the details of both their electronic structure and reactivity has been for decades one of the prime…

Electrochemical deposition of ZnO thin films in aprotic ionic liquids: Effect of the cationic alkyl-chain-length

Rita Khalil, Mirella Azar, Ibrahim Bou Malham, Mireille Turmine, Vincent Vivier

Zinc oxide (ZnO) is a semiconductor with various physicochemical properties allowing its use in a wide range of technological applications. The aim of this work is to study nanocrystalline ZnO thin-film deposited using zinc salt which is dissolved in pure ionic liquids (ILs). The latter play a dual…

Catalytic behavior of copper–amine complex supported on mesoporous silica SBA-15 toward mono-Aza-Michael addition: role of amine groups

Aboubakr Hakiki, Riad Mustpha Kerbadou, Bouhadjar Boukoussa, Hadjira Habib Zahmani, Franck Launay, Alain Pailleret, Françoise Pillier, Salih Hacini, Abdelkader Bengueddach, Rachida Hamacha

This work concerns the preparation and modification of mesoporous silica SBA-15 with different amine-copper complexes in order to study their impact on the catalytic behavior via Aza Michael addition. Firstly, SBA-15 was prepared hydrothermally, then functionalized by mono-, di- and tri-amine, and…

The Acidity of Zeolites: Concepts, Measurements and Relation to Catalysis: A Review on Experimental and Theoretical Methods for the Study of Zeolite Acidity

E.G. Derouane, Jacques C. Vedrine, Ramos R. Pinto, P.M. Borges, L. Costa, M. A. N. D. A. Lemos, F. Lemos, Ramôa Ribeiro

In this article, we considered all aspects of acidity (nature of acid sites, strength, density, etc.) in solid catalysts and in zeolites in particular. After reminding the definition of acidity in liquid and solid acids, we emphasized acidity characterization by the most used physical techniques,…
