Insights into the influence of the Ag loading on Al2O3 in the H2-assisted C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Guylène Costentin, Catherine Louis, Sandra Casale, Ruth L. Chantry, Z.Y. Li, Cyril Thomas

The addition of H2 has been reported to promote drastically the selective catalytic reduction of NOx by hydrocarbons (HC-SCR). Yet, the influence of the Ag loading on the H2-promoted HC-SCR has been the subject of a very limited number of investigations. The H2-HC-SCR earlier studies reported…

Vers une meilleure compréhension de la réduction sélective des oxydes d'azote par les hydrocarbures sur les catalyseurs à base d'argent et d'or supportés sur alumine, Towards a further understanding of the selective catalytic reduction of nitrogen oxides by propene on alumina supported silver and gold catalysts

Tesnim Chaieb

Ces travaux de thèse ont porté sur l'étude approfondie de catalyseurs à base d'argent et d'or dans la réduction catalytique sélective des NOx par C3H6. Pour le système Ag/Al2O3, nous avons réussi à fournir une explication rationnelle de l'origine de l'existence d'un…, This work provides further insights into C3H6-SCR on alumina supported silver and gold catalysts. The origin of the optimum loading of 2 wt% of Ag on Al2O3 in the C3H6-SCR of NOx was elucidated with the help of an original characterization method (NOx-TPD). The optimum loading was attributed to the…

Phosphate Boosts Nonhydroxyl Radical Species Production upon Air Oxidation of Magnetite and Iron Sulfides at Neutral pH

Guillaume Morin, Frédéric Averseng, Xavier Carrier, Pierre Le Pape, Yishan Du, Yusheng Honge, Elora Bourbon, Giuseppe Sportelli, Tiago A da Silva, Alberto Mezzetti, Camille Baya, Thierry Allard, Jessica Brest, Maryse Rouelle

Heterogeneous Fenton-like reactions using O2 as sole oxidant are gaining interest for designing organic contaminant degradation in soils and groundwaters, since they may provide alternatives to current processes involving strong oxidants. Indeed, several Fe(II)-bearing oxide and sulfide mineral…

Role of oxygen vacancies in the basicity of ZnO: From the model methylbutynol conversion to the ethanol transformation application

C. Drouilly, J.M. Krafft, F. Averseng, H. Lauron-Pernot, Delphine Bazer-Bachi, Céline Chizallet, V. Lecocq, Guylène Costentin

The parameters governing the basic reactivity of kadox and ex-carbonate zinc oxide samples towards alcohol conversion were investigated varying the atmosphere of pre-treatment for a model reaction, the methylbutynol (MBOH) conversion, and the ethanol conversion reaction, a transformation of…

Selective hydrodechlorination of 1,2-dichloroethane on NiSiBEA zeolite catalyst: Influence of the preparation procedure on a high dispersion of Ni centers

R. Baran, I.I. Kamińska, A. Śrębowata, S. Dzwigaj

NixSiBEA zeolites (x = 1-2 Ni wt.%) were prepared by a two-steps postsynthesis method which consists of (1) creation of vacant T-sites by dealumination of tetraethylammonium BEA zeolite with nitric acid and then (2) impregnation of resulting SiBEA zeolite with an aqueous solution of Ni(NO3)2,…

Beneficial effect of gelatin on iron gall ink corrosion

Alice Gimat, Anne Michelin, Pascale Massiani, Véronique Rouchon

Iron gall Inks corrosion causes paper degradation (browning, embrittlement) and treatments were developed to tackle this issue. They often include resizing with gelatin to reinforce the paper and its cellulosic fibers (of diameter approx. 10 µm). This work aimed at measuring the distribution of ink…

Intérêt des revêtements N-halamines dans la lutte contre le développement des bactéries et du biofilm

Catherine Debiemme-Chouvy, Shan Gao, Hubert Cachet, Nadia Nazi, Vincent Humblot

L’enrayement du développement des biofilms ou de la prolifération de bactéries pathogènes est indispensable aussi bien pour des raisons de santé publique que pour des raisons économiques. Pour les milieux hydriques, à ces fins, des biocides oxydants sont fréquemment employés. Ils sont alors ajoutés…

Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis

Yang Song, Sandra Casale, Antoine Miche, David Montero, Christel Laberty-Robert, David Portehault

We synthesize metal silicide electrocatalysts for water oxidation, by using the high reactivity of silicon nanoparticles and the unique stability and low vapor pressure of molten salt solvents. We can then perform liquid-phase synthesis under vacuum at 300-400 C. This strategy yields FeSi, Ni 2 Si…

We investigate the evolution of the surface of a highly alloyed stainless steel (Sanicro 28) upon immersion in aqueous phosphoric acid solutions. For this purpose, both short-(few hours) and long-term immersion (several days) were carried out. A detailed analysis of XPS spectra allowed a…
