In Situ Cobalt Speciation on γ-Al 2 O 3 in the Presence of Carboxylate Ligands in Supported Catalyst Preparation

A. Davantès, C. Schlaup, X. Carrier, Mickael Rivallan, G. Lefèvre

Molecular-scale understanding of metal impregnation on a porous oxide support is a key step toward the development of optimized (and cost ,effective) catalytic materials with enhanced activity, selectivity and time on stream stability. In the present contribution in situ ATR-IR and ex situ…

Effect of Cs impregnation on the properties of platinum in Pt/Na-BEA and Pt/Cs-BEA catalysts

Pascale Massiani, E.R. Silva, F.R. Ribeiro, M.F. Ribeiro, J.M. Silva

The presence of alkali cations in zeolite framework provides peculiar basic properties that influence the characteristics and reactivity of supported metal particles. Particularly, the addition of increasing amounts of cesium in Pt/Na-BEA and Pt/Cs-BEA catalysts, by CsOH impregnation, leads to…

Characterizations and performances of Ni/diatomite catalysts for dry reforming of methane

Karam Jabbour, Nissrine El Hassan, Anne Davidson, Pascale Massiani, Sandra Casale

Monometallic 5 wt% Ni containing catalysts were prepared by a two-solvent (cyclohexane/water) deposition method using cheap and widely available natural diatomites (Ni/AW2 and Ni/MN3) as supports. The fresh samples were characterized by SEM, EDX microanalysis, N2 adsorption–desorption isotherms,…

Catalytic hydrogen-assisted dehydrochlorination of 1,2-dichloroethane over cobalt-containing beta zeolite

Anna Śrębowata, Rafal Baran, Izabela I. Kamińska, Thomas Onfroy, Jean-Marc Krafft, Stanislaw Dzwigaj

HAlBEA zeolite obtained by calcination of parent TEABEA zeolite at 823 K for 3 h in air following ion exchange with NH4NO3 solution and calcination at 773 K for 3 h was used for synthesis of cobalt containing zeolite by conventional wet impregnation with an aqueous solution of Co(NO3)2. The…

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…

Design of Advanced Functional Materials Using Nanoporous Single‐Site Photocatalysts

Kohsuke Mori, Xufang Qian, Yasutaka Kuwahara, Yu Horiuchi, Takashi Kamegawa, Yixin Zhao, Catherine Louis, Hiromi Yamashita

Nanoporous silica solids can offer opportunities for hosting photocatalytic components such as various tetra-coordinated transition metal ions to form systems referred to as “single-site photocatalysts”. Under UV/visible-light irradiation, they form charge transfer excited states, which exhibit a…

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…
