Selectivities in Adsorption and Peptidic Condensation in the (Arginine and Glutamic Acid)/Montmorillonite Clay System

Maguy Jaber, Thomas Georgelin, Houssein Bazzi, France Costa-Torro, Jean-François Lambert, Gérard Bolbach, Gilles Clodic

The present study examines the selective adsorption and polymerization of two amino acids, glutamic acid (Glu) and arginine (Arg), on a cationic clay mineral, montmorillonite (Mt). Two experimental procedures were used: selective adsorption and wet impregnation. In the first case, an adsorption…

Mechanism of Metal Oxide Nanoparticle Loading in SBA-15 by the Double Solvent Technique

Juliette van Der Meer, Isabelle Bardez-Giboire, Cyrille Albert-Mercier, Bertrand Revel, Anne Davidson, Renaud Denoyel

The interaction between SBA-15 mesoporous silica, alkane solvents, and water was studied to understand the mechanism of the so-called double solvent technique. This method facilitates the loading of the pores of SBA-15 with a metal oxide precursor soln., by prewetting the SBA-15 with an alkane. In…

Influence of Magnesium Substitution on the Basic Properties of Hydroxyapatites

Sarah Diallo-Garcia, Danielle Laurencin, Jean-Marc Krafft, Sandra Casale, Mark E. Smith, Hélène Pernot, Guylène Costentin

Magnesium-substituted hydroxyapatites (HAP) have been prepared to evaluate the influence of cationic substitution on the surface basic properties of HAP. Despite successful introduction of some of the magnesium cations into the HAP structure (as evidenced by XRD, infrared, and Raman), no influence of…

Homogeneous and Heterogeneous Catalysis for the Synthesis of Cyclic and Polymeric Carbonates from CO2 and Epoxides: A Mechanistic Overview

Guillaume Laugel, Catarina Rocha Carvalho, Pascale Massiani, Thomas Onfroy, Franck Launay

The utilization of CO2 for the production of useful chemicals is nowadays considered as a promising way to contribute to the reduction of greenhouse gases in the atmosphere, while valorizing at the same time this widely available resource. The synthesis of cyclic carbonates and polycarbonates via…

Incorporation of vanadium into the framework of hydroxyapatites: importance of the vanadium content and pH conditions during the precipitation step

Sarah Petit, Thrimurthulu Gode, Cyril Thomas, Stanislaw Dzwigaj, Yannick Millot, Dalil Brouri, Jean-Marc Krafft, Gwenaelle Rousse, Christel Laberty-Robert, Guylène Costentin

Even though vanadium-modified hydroxyapatite (V-HAp) samples are very promising systems for oxidative dehydrogenation of propane, the incorporation of vanadium into the hydroxyapatite framework was reported to be limited and to lead to over-stoichiometric compounds. Here, the synthesis of a Ca10(…

In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…

No particle size effects in the electrochemical conversion of Co2 to formate on Sn electrodes

Carlos M Sánchez-Sánchez, A. Del Castillo, Manuel Alvarez-Guerra, Juliette Blanchard, A. Irabien

Recycling of CO2 emissions by direct electrocatalytic reduction of CO2 has been pointed out as a feasible method for CO2 conversion into useful chemical products and fuels. In particular, formic acid (HCOOH) represents one of the most interesting products obtained, since HCOOH is widely used in…
