Cu-modified hydroxy-apatite as catalyst for Glaser–Hay CC homo- coupling reaction of terminal alkynes

Birgit Maaten, Jamal Moussa, Christophe Desmarets, Patrick Gredin, Patricia Beaunier, Tõnis Kanger, Kaia Tõnsuaadu, Didier Villemin, Michel Gruselle

The oxidative Glaser–Hay coupling reaction of terminal alkynes is a very important reaction in organic chemistry to achieve the synthesis of diyne compounds. In general the reaction is performed under homogeneous conditions using Cu(I) or Cu(II) salts in the presence of a reagent such as…

Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis

Yang Song, Sandra Casale, Antoine Miche, David Montero, Christel Laberty-Robert, David Portehault

We synthesize metal silicide electrocatalysts for water oxidation, by using the high reactivity of silicon nanoparticles and the unique stability and low vapor pressure of molten salt solvents. We can then perform liquid-phase synthesis under vacuum at 300-400 C. This strategy yields FeSi, Ni 2 Si…

Towards the synthesis of mixed oxides with controlled stoichiometry from Prussian blue analogues

Virgile Trannoy, Amélie Bordage, Jordan Dezalay, Romuald Saint-Martin, Eric Rivière, Patricia Beaunier, Cédric Baumier, Camille La Fontaine, Giulia Fornasieri, Anne Bleuzen

Controlling the synthesis of mixed oxides is of great interest since their stoichiometry influences the properties. We present here the transformation of the Co4[Fe(CN)6]2.7 Prussian blue analogue (PBA) into the mixed Co1.8Fe1.2O4 spinel oxide, with a detailed characterization of the final phase (…

Polyol Process Coupled to Cold Plasma as a New and Efficient Nanohydride Processing Method: Nano-Ni 2 H as a Case Study

Sonia Haj-Khlifa, Sophie Nowak, Patricia Beaunier, Patricia de Rango, Michaël Redolfi, Souad Ammar-Merah

An alternative route for metal hydrogenation has been investigated: cold plasma hydrogen implantation on polyol-made transition metal nanoparticles. This treatment applied to a challenging system, Ni-H, induces a reordering of the metal lattice, and superstructure lines have been observed by both…

Hydroxyapatite: A Matrix for Metal Exsolution Leading to Highly Dispersed Catalytically Active Species

Josefine Schnee, Ferdaous Ben Romdhane, François Devred, Antoine Miche, Alixandre Magerat, Diane Reja, Eric Gaigneaux, Marco Daturi, Cyril Thomas, Guylène Costentin

Hydroxyapatite (Ca10(PO4)6(OH)2, or HAp) -the main mineral component of bones and teeth -is a material of great interest not only in biomedical applications but also in heterogeneous catalysis. Its framework Ca 2+ cations can be substituted by a wide variety of catalytically active metals (Cu 2+ ,…

Electrospray ionization: an efficient approach to deposit polymetallic molecular switches onto gold surfaces

Amina Benchohra, Christophe Méthivier, Jessem Landoulsi, David Kreher, Rodrigue Lescouëzec

Electrospray ionization (EI) deposition is proven efficient in obtaining monolayers of a polymetallic charge transfer complex onto gold surfaces. The molecule's integrity is monitored by PM-IRRAS and XPS. This approach broadens the perspective of molecular magnetic switches' deposition,…
