NOx-TPD as a Tool to Estimate the Accessible Zirconia Surface of ZrO2-Containing Materials

Hiu Ying Law, Juliette Blanchard, Xavier Carrier, Cyril Thomas

NOx adsorption-desorption experiments were carried out on a series of W-free and W-containing ZrO2 samples. To the best of our knowledge, this study establishes for the first time NOx-TPD (temperature-programmed desorption of NOx) as a reliable method to estimate the accessible ZrO2 surface of…

Supported gold catalysts for the decomposition of VOC: Total oxidation of propene in low concentration as model reaction

Laurent Delannoy, Katia Fajerwerg, Pandian Lakshmanan, Claude Potvin, Christophe Methivier, Catherine Louis

Supported gold catalysts prepared by deposition-precipitation with urea were studied in the reaction of oxidation of propene in low concentration in a large excess of oxygen, so as to mimic the conditions of catalytic decomposition of a volatile organic compound of hydrocarbon-type (1200 ppm C3H6,…

Vanadium-Substituted Phosphomolybdic Acids for the Aerobic Cleavage of Lignin Models-Mechanistic Aspect and Extension to Lignin

Louay Al-Hussaini, Franck Launay, Elena Galvez

This work deals with the aerobic oxidative cleavage of CC and CO bonds catalyzed by the Keggin-type phosphovanadomolybdic acid (H 6 [PMo 9 V 3 O 40 ], noted H 6 PV 3). The latter was synthesized by an adapted hydrothermal procedure classically used for lower vanadium content and was tested as a…

Hexacyano Ferrate (III) Reduction by Electron Transfer Induced by Plasmonic Catalysis on Gold Nanoparticles

Iyad Sarhid, Isabelle Lampre, Diana Dragoe, Patricia Beaunier, Bruno Palpant, Hynd Remita

Redox reactions are of great importance in environmental catalysis. Gold nanoparticles (Au-NPs) have attracted much attention because of their catalytic activity and their localized surface plasmon resonance (LSPR). In the present study, we investigated, in detail, the reduction of ferricyanide (…

Light-induced infrared difference spectroscopy on three different forms of orange carotenoid protein: focus on carotenoid vibrations

Silvia Leccese, Adjélé Wilson, Diana Kirilovsky, Riccardo Spezia, Claude Jolivalt, Alberto Mezzetti

Orange carotenoid protein (OCP) is a photoactive carotenoprotein involved in photoprotection of cyanobacteria, which uses a keto-catorenoid as a chromophore. When it absorbs blue-green light, it converts from an inactive OCPO orange form to an activated OCPR red form, the latter being able to bind…

Hydrodechlorination of 1,2-dichloroethane on nickel loaded Beta zeolite modified by copper: Influence of nickel and copper state on product selectivity

Rafal Baran, Anna Srebowata, Sandra Casale, D. Łomot, Stanislaw Dzwigaj

Influence of copper addition to nickel containing zeolite on activity and product selectivity in the hydrodechlorination of 1,2-dichloroethane was investigated. Ni2.0SiBEA and Cu2.0Ni2.0SiBEA zeolites were prepared by a two-steps postsynthesis method which consist of (1) creation of vacant T-atom…

Formation of Activated Biomolecules by Condensation on Mineral Surfaces – A Comparison of Peptide Bond Formation and Phosphate Condensation

Thomas Georgelin, Maguy Jaber, Houssein Bazzi, Jean-François Lambert

Many studies have reported condensation reactions of prebiotic molecules, such as the formation of peptide bonds between amino acids, to occur to some degree on mineral surfaces. We have studied several such reactions on the same divided silica. When drying steps are applied, the equilibria of…
