Electron transfers in a TiO₂-containing MOR zeolite: Synthesis of the nanoassemblies and application using a probe chromophore molecule

A. Legrand, A. Moissette, M. Hureau, S. Casale, P. Massiani, H. Vezin, A.S. Mamede, I. Batonneau-Gener

New assemblies constituted by a microporous matrix of mordenite (MOR) zeolite on which TiO₂ nanoclusters are deposited were synthesized using ionic oxalate complexes and TiCl₃ titanium precursors. The samples were used to investigate the transfer of…

Exploring the self-assembly of dumbbell-shaped polyoxometalate hybrids, from molecular building units to nanostructured soft materials

Mireia Segado Centellas, Madeleine Piot, Raphaël Salles, Anna Proust, Ludovic Tortech, Dalil Brouri, Sébastien Hupin, Benjamin Abécassis, David Landy, Carles Bo, Guillaume Izzet

The formation of hierarchical nanostructures using preformed dumbbell-like species made of covalent organic–inorganic polyoxometalate (POM)-based hybrids is herein described. In this system, the presence of charged subunits (POM, metal linkers, and counter ions) in the complex molecular…

A Material Perspective on HgTe Nanocrystal-based Short Wave Infrared Focal Plane Arrays

Huichen Zhang, Rodolphe Alchaar, Yoann Prado, Adrien Khalili, Charlie Gréboval, Mariarosa Cavallo, Erwan Bossavit, Corentin Dabard, Tung Huu Dang, Claire Abadie, Christophe Methivier, David Darson, Victor Parahyba, Pierre Potet, Julien Ramade, Mathieu Silly, James Utterback, Debora Pierucci, Sandrine Ithurria, Emmanuel Lhuillier

After the use of nanocrystals as light down-converters, infrared sensing appears to be one of the first market applications where they can be used while being both electrically and optically active. Over recent years, tremendous progress has been achieved, leading to an apparent rise in the…

Modifying protein adsorption by layers of glutathione pre-adsorbed on Au(111).

Anne Vallée, Vincent Humblot, Christophe Méthivier, Paul Dumas, Claire-Marie Pradier

Molecular interaction with metal surfaces raises fundamental questions regarding their binding tendency, their dispersion on the surface, as well as their conformation which may change their biological properties; addressing these questions, and being able to tune protein interactions, is of…

A new glance at ruthenium sorption mechanism on hydroxy, carbonate, and fluor apatites: Analytical and structural studies

K. Tõnsuaadu, M. Gruselle, F. Villain, R. Thouvenot, M. Peld, V. Mikli, R. Traksmaa, Patrick Gredin, Xavier Carrier, L. Salles

The sorption mechanism of Ru3+ ions on hydroxy (HAp), carbonate (CO3HAp), and fluor apatites (FAp) has been studied in detail. Ru apatites were obtained by reaction of the apatites with RuCl3 in aqueous solution. The structure and composition of the ruthenium-modified apatites were studied by…

Revisiting the Mukaiyama-type epoxidation for the conversion of styrene into styrene carbonate in the presence of O 2 and CO 2

Matthieu Balas, Asma Mayoufi, Richard Villanneau, Franck Launay

Since its first report in the early 1990s, Mukaiyama-type aerobic epoxidation involving the presence of an aldehyde as an electron donor is considered as an interesting oxidation reaction. Among the various metal catalysts efficient for this process, salen-type complexes have many advantages: i)…

Surface‐Dependent Activation of Model α‐Al2O3‐Supported P‐Doped Hydrotreating Catalysts Prepared by Spin Coating

Ricardo Garcia de Castro, Jérémy Bertrand, Baptiste Rigaud, Elodie Devers, Mathieu Digne, Anne‐félicie Lamic-Humblot, Gerhard Pirngruber, Xavier Carrier

Requirements for improved catalytic formulations is continuously driving research in hydrotreating (HDT) catalysis for biomass upgrading and heteroatom removal for cleaner fuels. The present work proposes a surface-science approach for the understanding of the genesis of the active (sulfide) phase…

C3-Alkylation of furfural derivatives by continuous flow homogeneous catalysis

Grédy Kiala Kinkutu, Catherine Louis, Myriam Roy, Juliette Blanchard, Julie Oble

The C3-functionalization of furfural using homogeneous ruthenium catalysts requires the preinstallation of an ortho -directing imine group, as well as high temperatures, which did not allow scaling up, at least under batch conditions. In order to design a safer process, we set out to develop a…

Design of simple salophen chromium complexes for a two-steps oxidative carboxylation of styrene with CO2 and O2

Matthieu Balas, Richard Villanneau, Franck Launay

In this work, chromium(III) Salophen complexes bearing tertiary dimethyl or diethyl amino substituents were synthesized and tested as homogeneous co-catalysts associated with n-Bu 4 NBr for the cycloaddition of CO 2 on styrene epoxide under 11 bar of CO 2. Full conversion of styrene oxide into…
