An UV-Visible study of the stability of the ruthenium hexaammine cation in BEA zeolites—comparison with NaY

Pascale Massiani, Perla Castillo-Villalon, Jorge Ramirez, Marie-Jeanne Peltre, Catherine Louis

A series of Ru/zeolites with Ru content in the range of 1–7 wt.% was prepared by cationic exchange in an aqueous Ru(NH3)6Cl3 solution, at room temperature, of two H–BEA (different particle sizes but same Si/Al ratio of 13), a Cs–BEA (Si/Al 1⁄4 13) and a NaY (Si/Al 1⁄4 2.4), zeolitic supports. The…

PdAg alloy nanoparticles encapsulated in N-doped microporous hollow carbon spheres for hydrogenation of CO2 to formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

Here, we report a general synthesis approach to produce PdAg nanoparticles (NPs) that are dispersed uniformly within N-doped microporous hollow carbon spheres (NMHCS) for hydrogenation of CO2 to formate. The optimized PdAg@NMHCS catalyst, which was obtained by using an optimized amount of…

Unlocking synergy in bimetallic catalysts by core–shell design

Jessi van der Hoeven, Jelena Jelic, Liselotte Olthof, Giorgio Totarella, Relinde van Dijk-Moes, Jean-Marc Krafft, Catherine Louis, Felix Studt, Alfons van Blaaderen, Petra de Jongh

Extending the toolbox from mono- to bimetallic catalysts is key in realizing efficient chemical processes1. Traditionally, the performance of bimetallic catalysts featuring one active and one selective metal is optimized by varying the metal composition1,2,3, often resulting in a compromise between…

On the Comprehensive Precipitation of Hydroxyapatites Unraveled by a Combined Kinetic–Thermodynamic Approach

Corentin Reynaud, Cyril Thomas, Guylène Costentin

The present study combines experimental and theoretical approaches to investigate the competitive precipitation of calcium phosphates (CaPs) in aqueous solution in order to understand and control both the structural and textural properties of the synthesized hydroxyapatites (HAps). Some of the…

A fullerene helical peptide: synthesis, characterization and formation of self-assembled monolayers on gold surfaces

Houssein Nasrallah, Jad Rabah, Van Bui-Thi-Tuyet, Krystyna Baczko, Hélène Fensterbank, Flavien Bourdreux, Anne-Marie Goncalves, Valérie Declerck, Souhir Boujday, Vincent Humblot, Karen Wright, Anne Vallée, Emmanuel Allard

The synthesis of a C60-peptide using "clickable" fullerene and peptide derivatives is described. The peptide is composed of a repeating sequence of -aminoisobutyric acid (Aib) and two L-Alanine (Ala) residues, promoting the formation of a helical conformation, which has been confirmed by…

Hydrodechlorination of 1,2-dichloroethane on nickel loaded Beta zeolite modified by copper: Influence of nickel and copper state on product selectivity

Rafal Baran, Anna Srebowata, Sandra Casale, D. Łomot, Stanislaw Dzwigaj

Influence of copper addition to nickel containing zeolite on activity and product selectivity in the hydrodechlorination of 1,2-dichloroethane was investigated. Ni2.0SiBEA and Cu2.0Ni2.0SiBEA zeolites were prepared by a two-steps postsynthesis method which consist of (1) creation of vacant T-atom…
