Activation of C‐H Bond of Propane by Strong Basic Sites Generated by Bulk Proton Conduction on V‐Modified Hydroxyapatites for the Formation of Propene

Sarah Petit, Cyril Thomas, Yannick Millot, Jean-Marc Krafft, Christel Laberty-Robert, Guylène Costentin

Insights into the catalytic transformation of propane to propene on V‐apatites catalysts are provided based on structure‐reactivity relationships. Substitution of phosphates by vanadates in the hydroxyapatite structure leads to the formation of Ca10(PO4)6‐x(VO4)x(OH)2‐yOy V‐oxy‐hydroxy‐apatite…

Time-resolved infrared absorption spectroscopy applied to photoinduced reactions: how and why

Alberto Mezzetti, Josefine Schnee, Andrea Lapini, Mariangela Di Donato

Time-resolved infrared (IR) spectroscopy is a widely used technique in the investigation of photoinduced reactions, given its capabilities of providing structural information about the presence of intermediates and the reaction mechanism. Despite the fact that it is used in several fields since the…

Conception raisonnée de catalyseurs bifonctionnels : élaboration de catalyseurs Pt0/zéolithe-Alumine, Rational design of bifunctional catalysts : development of Pt0/zeolithe-alumina catalysts

Olfa Ben Moussa

Les catalyseurs bifonctionnels pour l’hydrocraquage nécessitent à la fois des sites acides de Brønsted et des sites métalliques. L’intimité entre sites acides et sites métalliques peut donc influer sur l’activité et la sélectivité de la réaction. Nous nous sommes proposés d’explorer l’effet de la…, Bifunctional hydrocracking catalysts require both Brønsted acid sites and metal sites. Hence, the intimacy between acid sites and metal sites can influence the activity and selectivity of the reaction. We intended to explore the effect of metal sites-acid sites distance on the conversion of n…

Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

Identification of the silver state in the framework of Ag-containing zeolite by XRD, FTIR, photoluminescence, 109 Ag NMR, EPR, DR UV-vis, TEM and XPS investigations

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Rafal Baran, Yannick Millot, Stanislaw Dzwigaj

Silver has been identified in the framework of AgxSiBEA zeolites (where x = 3–6 Ag wt%) by the combined use of XRD, 109Ag MAS NMR, FTIR, diffuse reflectance UV-visible, EPR and XPS spectroscopy. The incorporation of Ag ions into the framework of SiBEA zeolite has been evidenced by XRD. The…

Using Prussian blue analogue nanoparticles confined into ordered mesoporous silica monoliths as precursors of oxides

Virgile Trannoy, Émilie Delahaye, Giulia Fornasieri, Patricia Beaunier, Anne Bleuzen

Powdered Prussian blue analogues (PBAs) and PBAs confined in ordered mesoporous silica monoliths were used as oxide precursors through thermal treatment under an oxidizing atmosphere. The study focuses on the transformation of the alkali cation-free CoCo PBA of chemical formula K0.1CoII4[CoIII(CN)6…

Coordination chemistry approach for the end-to-end assembly of gold nanorods

P.R. Selvakannan, Eddy Dumas, Frédéric Dumur, Christine Péchoux, Patricia Beaunier, Arnaud Etcheberry, Francis Secheresse, Hynd Remita, Cédric Mayer

Gold nanorods synthesized by radiolysis were selectively end-functionalized by a fully conjugated thiol bearing a pendant terpyridine group; addition of ferrous ions led to the end-to-end 1D self-assembly of the nanorods. Similar results have been obtained when the preformed [(HStpy)Fe(tpySH)](2+)…

Development of novel cathode materials for the bioelectrocatalysis of oxygen reduction reaction by laccase from Trametes versicolor

Achraf Blout, Alain Pailleret, Claude Jolivalt

Biocatalysts such as enzymes or bacteria constitute an attractive alternative to transition metal catalysts. They have several advantages as they often possess a better selectivity and higher catalytic performances and they can be used in different types of electrochemical devices such as fuel…

Rh-Ni/SBA-15 prepared by two solvents method as stable catalysts for the dry reforming of methane at high pressure

M.N. Kaydouh, El Hassan N., Elzakhem H., Anne Davidson, Sandra Casale, Pascale Massiani

The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced…
