Simple procedure for vacant POM-stabilized palladium (0) nanoparticles in water: structural and dispersive effects of lacunary polyoxometalates

R. Villanneau, A. Roucoux, P. Beaunier, D. Brouri, A. Proust

Metallic palladium nanoparticles have been generated by hydrogenation with H2 of solutions of several non organometallic PdII-derivatives of heteropolytungstates, at ambient temperature and atmospheric pressure. These nanoparticles have been characterized by various techniques: 31P NMR and Raman…

Surface orientation dependent interaction of cobalt (II) precursors with alpha-alumina

Céline Chizallet, Christian Schlaup, Emiliano Fonda, Xavier Carrier

The performances of alumina-supported cobalt catalysts strongly depend on Co/alumina interactions, that are poorly understood. In the present work, α-alumina surfaces are used as models of polycrystalline support, to unravel their orientation dependent behavior by GI-EXAFS. The CoII/α-alumina…

Hydrolysis of Ammonia-Borane over Ni/ZIF-8 Nanocatalyst: High Efficiency, Mechanism, and Controlled Hydrogen Release

Changlong Wang, Jimena Tuninetti, Zhao Wang, Chen Zhang, Roberto Ciganda, Lionel Salmon, Sergio Moya, Jaime Ruiz, Didier Astruc

Non-noble metal nanoparticles are notoriously difficult to prepare and stabilize with appropriate,dispersion, which in ttirn severely limits their catalytic functions. Here, using zeolitic imidazolate framework (ZIF-8) as MOF template, catalytically remarkably- efficient, ligand-free first-row late…

NO2 disproportionation for the IR characterisation of basic zeolites

Olivier Marie, Nicolas Malicki, Catherine Pommier, Pascale Massiani, Ann Vos, Robert Schoonheydt, Paul Geerlings, Carlos Henriquese, Frédéric Thibault-Starzyk

NO2 disproportionation on alkaline zeolites is used to generate nitrosonium (NO+) and nitrate ions on the surface, and the infrared vibrations observed are very sensitive to the cation chemical hardness and to the basicity of zeolitic oxygen atoms.side pockets of acidic mordenite. We describe here…

Selective Oxidation of Methane to Formaldehyde Catalyzed by Phosphates: Kinetic Description by Bond Strengths and Specific Total Acidities

Vasilij Gomonaj, Hervé Toulhoat

A kinetic model predicts the experimental activity and selectivity patterns obtained in oxidation of methane for divided unsupported orthophosphates (M II 3(PO4)2, M III PO4,) and pyrophosphates (M II 2P2O7, M IV P2O7) catalysts spanning extended ranges of M-O bond strength (calculated from first…

Corrosion and protection of high leaded tin bronze covered with patina in NaHCO3 + Na2SO4 solution simulating acid rain in urban environment

Kamal Rahmouni, Suzanne Joiret, Luc Robbiola, A. Srhiri, Hisasi Takenouti, Vincent Vivier

An experimental procedure for obtaining reproducible patina on high leaded tin bronze, B66 (Cu-8Sn-14Pb in wt %) has been devised, followed by its isolation from the substrate and examination of the electrochemical behaviour in a solution of 0.2 g.L - 1 Na 2 SO 4 + 0.2 g.L - 1 NaHCO 3 acidified to…

Approche expérimentale et théorique de l'inhibition de corrosion de surfaces métalliques, Experimental and theoretical approach of corrosion inhibition of metallic surfaces

Pauline Cornette

La corrosion des surfaces d’aluminium et d’alliages aluminium/cuivre, et notamment la corrosion localisée, est un problème majeur dans l’industrie, et l’utilisation d’inhibiteur de corrosion est bien souvent indispensable. Les chromates remplissent parfaitement leurs rôles d’inhibition mais seront…, Corrosion of aluminum and aluminum/copper alloy surfaces, including localized corrosion, is a major problem in the industry, and the use of a corrosion inhibitor is often essential. Chromates perfectly fulfill their role of inhibition but will soon be prohibited because of their toxicities for…

Synthesis of metal oxide catalysts

Xavier Carrier, Sébastien Royer, E. Marceau

This chapter gives an overview of the current preparation strategies for the synthesis of bulk and supported metal oxide catalysts, in order to give rational guides to understand the synthetic challenges associated with the preparation of these catalytic systems developed in the successive chapters…
