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…

Stabilization of hexagonal close-packed metallic nickel for alumina-supported systems prepared from Ni(II) glycinate

Eric Marceau, Vicente Rodriguez-Gonzalez, Michel Che, Patricia Beaunier, Cyrille Train

The decomposition in flowing argon of the neutral complex [NiII(glycinate)2(H2O)2] leads to a mixture of face-centered cubic (fcc) and hexagonal close-packed (hcp) metallic nickel. The latter is the main phase when the Ni(II) complex is supported on alumina. Unlike most hexagonal Ni phases…

Defects in ZnO nanoparticles obtained by gas-phase syntheses, Défauts dans les nanoparticules de ZnO obtenues par synthèses en phase gazeuse

Miao Zhang

By far, the assignment of defects-related spectroscopic features of zinc oxide is still a matter of great controversy. This is probably due to the variety of possible defects in ZnO as well as to their still uncertain formation energies and positions within the band gap. Uncontrolled measurement…, L’attribution des signatures spectrales liées aux défauts dans l’oxyde de zinc fait encore l’objet de controverses. Ceci est probablement dû à la grande variété de défauts possibles, à l’incertitude de leur niveau d’énergie ainsi que leur énergie de formation dans la bande interdite. De plus, l’…

Hydrothermally stable Pd/SiO2@Zr Core@Shell catalysts for diesel oxidation applications

Chih-Han Liu, Junjie Chen, Todd Toops, Jae-Soon Choi, Cyril Thomas, Michael Lance, Eleni Kyriakidou

Hydrothermally stable diesel oxidation catalysts (DOCs) with improved low-temperature activity are desired for the abatement of emissions from diesel vehicles. Herein, novel palladium(Pd)/SiO2(core)@Zr(shell) structured DOCs were developed. SiO2 was completely covered by an 8.4 nm thickness Zr-…

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…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…
