Activation of C‐H Bond of Propane by Strong Basic Sites Generated by Bulk Proton Conduction on V‐Modified Hydroxyapatites for the Formation of Propene

Sarah Petit, Cyril Thomas, Yannick Millot, Jean-Marc Krafft, Christel Laberty-Robert, Guylène Costentin

Insights into the catalytic transformation of propane to propene on V‐apatites catalysts are provided based on structure‐reactivity relationships. Substitution of phosphates by vanadates in the hydroxyapatite structure leads to the formation of Ca10(PO4)6‐x(VO4)x(OH)2‐yOy V‐oxy‐hydroxy‐apatite…

Heteroaggregation and Selective Deposition for the Fine Design of Nanoarchitectured Bifunctional Catalysts: Application to Hydroisomerization

Olfa Ben Moussa, Lionel Tinat, Xiaojing Jin, Walid Baaziz, Olivier Durupthy, Celine Sayag, Juliette Blanchard

We successfully prepared bifunctional catalysts with the distance between metallic and acid sites tuned at the nanometer scale. Sols of β-zeolite nanoparticles were synthesized and mixed in optimized conditions with a γ-AlOOH boehmite suspension to yield alumina/zeolite aggregates with a nanometer…

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 (…

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…

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…

Corrosion of Old Overhead Lines: Insights into Aluminum-Steel Galvanic Couple Using Electrochemical Techniques

Divino Salvador Ramírez Rico, Stéphane Heurtault, Julien Said, Yuelin Xie, Mireille Turmine, Vincent Vivier

In order to explain the corrosion inside 20 th century power lines, the galvanic corrosion of steel and aluminum from 1949 was examined. In this investigation, 0.1 M Na2SO4 + 1 mM NaCl was used as moderately corrosive medium. Various electrochemical methods were applied to determine the corrosion…
