Characterization of mesoporous alumina prepared by surface alumination of SBA-15

Manuel Baca, Emmanuel de La Rochefoucauld, Emmanuelle Ambroise, Jean-Marc Krafft, Redouane Hajjar, Pascal P. Man, Xavier Carrier, Juliette Blanchard

Mesoporous aluminas of controlled pore sizes were synthesized by multiple grafting of Al isopropoxide in organic solvents on mesoporous silica SBA-15. These materials were characterized by N2 physisorption, TEM, XRD, 27Al NMR and their surface chemical properties were probed by DRIFT, cumene…

On the promotional effect of Pd on the propene-assisted decomposition of NO on chlorinated Ce0.68 Zr0.32 O2

Cyril Thomas, Olivier Gorce, Céline Fontaine, Jean-Marc Krafft, Françoise Villain, Gérald Djéga-Mariadassou

The selective catalytic reduction (SCR) of NOx assisted by propene is investigated on Pd/Ce0.68 Zr0.32 O2 catalysts (Pd/CZ), and is compared, under identical experimental conditions, with that found on a Pd/SiO2 reference catalyst. Physico-chemical characterisation of the studied catalysts along…

ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…

Co-grafting of antiadhesive and antimicrobial agents onto UV-micropatterned copper surfaces

Jessie Peyre, Vincent Humblot, Christophe Méthivier, Jean-Marc Berjeaud, Claire-Marie Pradier

Adhesion of proteins and bacteria was reduced by a factor close to one order of magnitude, and adhered bacteria were dramatically damaged on copper surfaces by grafting a PEG-modified PMMA-based (polymethyl methacrylate) copolymer together with an antimicrobial peptide. To obtain PEG and a peptide…

The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

Jadid E. Samad, Juliette Blanchard, Celine Sayag, Catherine Louis, John R. Regalbuto

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

Ultrafast time-resolved quantum cascade laser diagnostic for enlightening the role of surface formate species in the photocatalytic oxidation of methanol

Josefine Schnee, Marco Daturi, Mohamad El-Roz

In the present work, a new quantum cascade laser (QCL)-assisted operando FT-IR setup was used to get direct insight into the relationship between the overall catalytic performance of TiO2 photocatalysts in the gas phase photooxidation of methanol at 25 °C, and the kinetics of intermediate surface…

Comprehension of cellulose depolymerisation mechanisms induced by iron ions, Compréhension des mécanismes de dépolymérisation de la cellulose induits par les ions fer

Alice Gimat

Degradation of paper by iron gall inks (IGI) is a challenging issue for written heritage conservation. These inks consist of a mixture of iron(II) sulphate, tannins and gum Arabic, and are therefore acidic and iron-rich. Hence, paper degradation by IGI is often attributed to a combination of acid…, La dégradation du papier par les encres ferrogalliques (EFG) est un défi pour la conservation du patrimoine écrit. Ces encres, composées d'un mélange de sulfate de fer (II), de tannins et de gomme Arabique, sont acides et riches en fer. Par conséquent, les mécanismes de dégradation des…
