Macroscopic Magnetic Anisotropy Induced by the Combined Control of Size, Shape and Organization of NiFe Prussian Blue Analog Nanoparticles in an Ordered Mesoporous Silica Monolith

Robinson Moulin, Giulia Fornasieri, Marianne Impéror-Clerc, Eric Rivière, Patricia Beaunier, Anne Bleuzen

Integration of coordination polymers and metal–organic frameworks into real applications requires a processing step at the nanoscale. However, their synthesis in the form of nanoparticles with controlled size, shape and organization remains a challenge faced by diverse scientific communities.…

EXAFS spectroscopy as a tool to probe metal–support interaction and surface molecular structures in oxide-supported catalysts: application to Al2O3-supported Ni(ii) complexes and ZrO2-supported tungstates

Xavier Carrier, Eric Marceau, Hugo Carabineiro, Vicente Rodríguez-González, Michel Che

EXAFS spectroscopy is shown as a tool of prime importance to probe the formation of metal–oxygen–support bonds and unravel the surface molecular structure in oxide-supported systems through two examples: (i) a molecular metal complex (Ni(II) bisglycinate) characterized after impregnation and drying…

Formation of heteropolymolybdates during the preparation of Mo and NiMo HDS catalysts supported on SBA-15: Influence on the dispersion of the active phase and on the HDS activity

Alvaro Sampieri, Stephane Pronier, Sylvette Brunet, Xavier Carrier, Catherine Louis, Juliette Blanchard, Katia Fajerwerg, Michele Breysse

Mo and Ni-Mo sulfides in SBA-15 and Al-SBA-15 catalysts were prepd. by incipient wetness co-impregnation of molybdenum and nickel precursors (followed by thermal treatment under He at 823 K) and sulfidation under 10% H2S/H2 at 673 K. Only incipient wetness impregnation of Mo on pure silica SBA-15…

Chemical nature and thermal decomposition behavior of tartaric acid multilayers on rutile TiO 2 (110)

Elisa Meriggio, Rémi Lazzari, Christophe Méthivier, Pascal David, Stéphane Chenot, Xavier Carrier, Gregory Cabailh, Vincent Humblot

R,R-tartaric acid (RR-TA) thermal stability and decomposition on the rutile TiO2(110) surface was investigated by temperature programmed desorption. The authors show that a majority of RR-TA molecules are desorbed intact from multilayers at around 340 K, while they decompose from the first…

Biomineralization Patterns of Intracellular Carbonatogenesis in Cyanobacteria: Molecular Hypotheses

Jinhua Li, Isabel Margaret-Oliver, Nithavong Cam, Thomas Boudier, Marine Blondeau, Eric Leroy, Julie Cosmidis, Feriel Skouri-Panet, Jean-Michel Guigner, Céline Férard, Melanie Poinsot, David Moreira, Purificacion Lopez-Garcia, Corinne Cassier-Chauvat, Franck Chauvat, Karim Benzerara

The recent discovery of intracellular carbonatogenesis in several cyanobacteria species has challenged the traditional view that this process was extracellular and not controlled. However, a detailed analysis of the size distribution, chemical composition and 3-D-arrangement of carbonates in these…
