Metal–Support Interactions in Pt-WO 3 Heterostructures: Role of WO 3 Polymorphism

Isabel Gómez-Recio, Cyril Thomas, Christophe Méthivier, María Luisa Ruiz-González, José González-Calbet, David Portehault

Ionic exchange under soft conditions yields nanoplatelets of tungsten bronzes with an original crystal structure doped with cobalt, copper, platinum, and cesium cations (h′-MxWO3). The optimal orientation of the tunnel-based crystal structure, perpendicular to the basal plane of the nanoplatelets,…

Heterostructured Cobalt Silicide Nanocrystals: Synthesis in Molten Salts, Ferromagnetism, and Electrocatalysis

Yang Song, Isabel Gómez-Recio, Anissa Ghoridi, Fernando Igoa Saldaña, Daniel Janisch, Capucine Sassoye, Vincent Dupuis, David Hrabovsky, M. Luisa Ruiz-González, José González-Calbet, Sandra Casale, Andrea Zitolo, Benedikt Lassalle-Kaiser, Christel Laberty-Robert, David Portehault

Nanoscale heterostructures of covalent intermetallics should give birth to a wide range of interface-driven physical and chemical properties. Such a level of design however remains unattainable for most of these compounds, due to the difficulty to reach a crystalline order of covalent bonds at the…

Transition metal borides of Ni-B (Co-B) as alternative non-precious catalytic materials: Advances, potentials, and challenges. Short review

Marek Lewandowski, Maria Bartoszewicz, Karolina Jaroszewska, Gérald Djéga-Mariadassou

This review gives a brief presentation of the types, structure, synthesis, and application of amorphous transition metal borides (Mt-B) in particular the bulk or supported nickel and cobalt borides (NiB and CoB). Mt-B materials are amorphous metal-metalloid alloys and constitute an important group…

Investigation of the interface in silica-encapsulated liposomes by combining solid state NMR and first principles calculations.

Nicolas Folliet, Claire Roiland, Sylvie Bégu, Anne Aubert, Tzonka Mineva, Annick Goursot, Kaliaperumal Selvaraj, Luminita Duma, Frederik Tielens, Francesco Mauri, Guillaume Laurent, Christian Bonhomme, Christel Gervais, Florence Babonneau, Thierry Azaïs

In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

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

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…
