Progress on electrochemical and photoelectrochemical urea and ammonia conversion from urine for sustainable wastewater treatment

Sophia Akkari, Carlos M. Sánchez-Sánchez, Guillaume Hopsort, Karine Groenen Serrano, Karine Loubière, Théodore Tzedakis, Raihana Benyahia, Lamia Rebiai, Stéphane Bastide, Christine Cachet-Vivier, Vincent Vivier, Melissa Lopez-Viveros, Sam Azimi

The valorization of urine through the electro-oxidation of urea offers a promising alternative for industrial wastewater treatment plants. This operation, implemented at room temperature, allows, in addition to the depolluting action, the generation of hydrogen at the cathode. Using inexpensive…

Effect of pH on the incorporation of acrylic acid units in the core of polymer nanoparticles prepared by PISA and on their morphology

Clément Debrie, Noémie Coudert, Jean-Michel Guigner, Fanny Coumes, Clément Guibert, Simon Harrisson, François Stoffelbach, Olivier Colombani, Jutta Rieger

Polymerization-induced self-assembly (PISA) is a polymerization process in which amphiphilic block copolymers are simultaneously synthesized and self-assembled in a selective solvent, leading to nanoparticles of different morphologies. Copolymerization has been reported as a means to tune…

Adsorption of L-Lysine on Cu(110): A RAIRS study from UHV to the liquid phase

Vincent Humblot, Christophe Méthivier, Claire-Marie Pradier

Adsorption of L-Lysine on a Cu(110) surface has been investigated under UHV condition from sublimation of a crystalline phase. The adsorption was characterised by Fourier Transform Reflection Absorption Infrared Spectroscopy (FT-RAIRS) during exposure and Auger Electron Spectroscopy (AES). At room…

Carbon black composites—supports of HDS catalysts

P. Gheek, S. Suppan, J. Trawczynski, A. Hynaux, Celine Sayag, G. Djéga-Mariadassou

HDS activity of sulfided Mo (W) catalysts supported on carbon black composites (CBC) is affected by kind of functional groups present on the CBC surface. Oxidation of CBC with (NH4)2S2O8 produce functionalities with the highest acid strength and corresponding catalyst exhibits the highest HDS…

Kinetic study of the deep hydrodesulfurization of dibenzothiophene over molybdenum carbide supported on a carbon black composite: Existence of two types of active sites

A. Hynaux, Celine Sayag, S. Suppan, J. Trawczynski, M. H. Lewandowski, A. Szymanska-Kolasa, G. Djéga-Mariadassou

Hydrodesulfurization (HDS) is part of the hydrotreating process, which is an ensemble of several reactions (HDN, HDO, HDS, etc.) taking place simultaneously at the industrial scale. Only sulfur is currently submitted to drastic Europeans specifications and conventional commercial catalysts cannot…

Sorption of Cu(II) onto vineyard soils: macroscopic and spectroscopic investigations

Eric Marceau, Lorenzo Stievano

The sorption of Cu on five vineyard soils was examined via macroscopic and spectroscopic investigations. The composition of the soils was previously determined using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). X-ray absorption spectroscopy (XAS) was employed to determine the…

A DNA biosensor based on peptide nucleic acids on gold surfaces

Eva Mateo-Marti, C. Briones, Claire-Marie Pradier, Jose A. Martin-Gago

We present a DNA biosensor based on self assembled monolayers (SAMs) of thiol-derivatized Peptide nucleic acid (PNA) chains adsorbed on gold surfaces for recognizing complementary ssDNA. PNA molecules tend to realign their molecular axes parallel to the surface normal and form SAMs on gold surfaces…

1H MAS NMR study of the coordination of hydroxyl groups generated upon adsorption of H2O and CD3OH on clean MgO surfaces

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jocelyne Maquet, Michel Che

The coordination of OH groups on MgO has been characterized by 1H MAS NMR after appropriate pre-treatment conditions to obtain surfaces free from carbonates and with a controlled degree of hydroxylation. On MgO-sol–gel sample treated at 1023 K under flowing nitrogen, hydroxylated with water and…

Thermodynamic brønsted basicity of clean MgO surfaces determined by their deprotonation ability: Role of Mg2+–O2 pairs

Céline Chizallet, Marie Laurence Bailly, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Michel Che

The deprotonation ability of clean (i.e., carbonate- and hydroxyl-free) MgO surfaces of various morphologies towards protic molecules, such as propyne and methanol, is evaluated by following the adsorption modes and amount of dissociated species by FTIR. Photoluminescence is used to identify the…

The aim of this work was to develop a heterogeneous chemoenzymatic catalyst based on the use of Metal-Organic Frameworks (MOFs) as support for the eco-friendly amination of alcohols in a one-pot cascade synthesis. The cascade process is divided into two steps: an alcohol oxidation chemically…, L'objectif de ce travail était de développer un catalyseur chimio-enzymatique hétérogène basé sur l'utilisation de polymères de coordination poreux (ou Metal-Organic Framework: MOF) comme supports pour l'amination durable d'alcools à travers un procédé en cascade réalisé en une…
