Heteropolytungstate-decorated core-shell magnetic nanoparticles: A covalent strategy for polyoxometalate-based hybrid nanomaterials

Ourania Makrygenni, Emilie Secret, Aude Michel, Dalil Brouri, Vincent Dupuis, Anna Proust, Jean-Michel Siaugue, Richard Villanneau

Amino-functionalized core-shell magnetic nanoparticles have been covalently grafted with Polyoxometalates (POMs). These multifunctional nanocomposites have been obtained through the coupling of heteropolytungstate-based hybrids bearing carboxylic acid functions with aminopropyl functions that…

Photocatalyseurs nanocomposites UCNP@SiO2@ZnO, activés par rayonnement proche infrarouge, pour la dépollution des eaux usées, Nanocomposites photocatalysts UCNP@SiO2@ZnO, active under near-infrared light, for wastewater treatment

David Hu

Les photocatalyseurs tels que l’oxyde de zinc (ZnO) peuvent minéraliser les polluants organiques toxiques et persistants dans les eaux usées. Ils ne sont cependant pas efficients dans les eaux très contaminées, suite à la nécessité d’une activation par une lumière UV qui n’y pénètre que faiblement…, Photocatalysts such as zinc oxide (ZnO) can mineralize toxic and persistent organic pollutants present in wastewaters. Unfortunately, these photocatalysts loose part of their effectiveness because they need to be activated by UV light, which has a limited penetration depth in highly contaminated…

l-Methionine adsorption on Cu(110), binding and geometry of the amino acid as a function of coverage

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

The adsorption of l-methionine on Cu(110) has been characterized by combining in situ Polarization Modulation Infrared Reflection Absorption Spectroscopy (PM-IRRAS) and X-ray Photoelectron Spectroscopy (XPS). Both the chemical state of the molecule, and its anchoring points were determined at…

Catalytic conversion of trichloroethylene on nickel containing beta zeolites into value added products

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

Nickel containing BEA zeolites, NiSiBEA and NiHAlBEA, with 2 wt% of Ni were prepared by a two-step postsynthesis method and conventional wet impregnation. The calcination of NiSiBEA and NiHAlBEA at 773 K for 3 h in air led to the formation of C-NiSiBEA and C-NiHAlBEA. After reduction at 873 K for 3…

Compared activity and stability of three Ni-silica catalysts for methane bi- and dry reforming

Karam Jabbour, M.N. Kaydouh, N El Hassan, H El Zakhem, Sandra Casale, Anne Davidson, Pascale Massiani

A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at…

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…

Additive-Free Aqueous Phase Synthesis of Formic Acid by Direct CO 2 Hydrogenation over a PdAg Catalyst on a Hydrophilic N-Doped Polymer–Silica Composite Support with High CO 2 Affinity

Shinya Masuda, Kohsuke Mori, Yasutaka Kuwahara, Catherine Louis, Hiromi Yamashita

A series of N-doped polymer containing silica (NPS) materials were synthesized via condensation reactions of 3-aminopropyltriethoxysilane (APT) and various aldehydes. These materials were assessed as supports for a PdAg alloy catalyst intended to promote the CO2 hydrogenation reaction under…
