Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

Silica-Supported Au-Ag Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Christophe Calers, Jean-Jacques Gallet, Fabrice Bournel, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Gold and silver are miscible over the entire composition range, and form an attractive combination for fundamental studies on bimetallic catalysts. Au–Ag catalysts have shown synergistic effects for different oxidation and liquid-phase hydrogenation reactions, but have rarely been studied for gas…

Influence of the nature and environment of vanadium in VSiBEA zeolite on selective catalytic reduction of NO with ammonia

R. Baran, T. Onfroy, T. Grzybek, S. Dzwigaj

The influence of the nature and environmental of vanadium on the catalytic properties of VxSiBEA zeolite in selective catalytic reduction of NO with ammonia is investigated. Catalysts containing 1-7.5 wt.% of vanadium were prepared by a two-step postsynthesis method which consists, in the first…

Enhancing low-temperature activity and durability of Pd-based diesel oxidation catalysts using ZrO2 supports

Mi-Young Kim, Eleni A. Kyriakidou, Jae-Soon Choi, Todd J. Toops, Andrew J. Binder, Cyril Thomas, James E. Parks, Viviane Schwartz, Jihua Chen, Dale K. Hensley

We investigated the impact of ZrO2 on the performance of palladium-based oxidation catalysts with respect to low-temperature activity, hydrothermal stability, and sulfur tolerance. Pd supported on ZrO2 and SiO2 were synthesized for a comparative study. Additionally, in an attempt to maximize the…

Selective catalytic reduction of NO on single site FeSiBEA zeolite catalyst: Influence of the C1 and C2 reducing agents on the catalytic properties

Janusz Janas, Wojciech Rojek, Tetsuya Shishido, Stanislaw Dzwigaj

FeSiBEA zeolite with 0.8 Fe wt% is prepared in acidic condition (pH 2.5) by a two-step postsynthesis method which allows to incorporate iron into framework of zeolite as mononuclear distorted tetrahedral Fe(III) species, as evidenced by XRD, diffuse reflectance UV-vis and X-ray absorption…

On the promotional effect of Pd on the propene-assisted decomposition of NO on chlorinated Ce0.68 Zr0.32 O2

Cyril Thomas, Olivier Gorce, Céline Fontaine, Jean-Marc Krafft, Françoise Villain, Gérald Djéga-Mariadassou

The selective catalytic reduction (SCR) of NOx assisted by propene is investigated on Pd/Ce0.68 Zr0.32 O2 catalysts (Pd/CZ), and is compared, under identical experimental conditions, with that found on a Pd/SiO2 reference catalyst. Physico-chemical characterisation of the studied catalysts along…
