Ag–Ni bimetallic SiBEA zeolite as an efficient catalyst of hydrodechlorination of 1,2-dichloroethane towards ethylene

A Śrębowata, I Zielińska, R Baran, G Słowik, S Dzwigaj

Dealuminated form of BEA zeolite with Si/Al ratio of 1500 was used for the synthesis of Ag2.0SiBEA, Ni2.0SiBEA and Ag2.0Ni2.0SiBEA by two-step postsynthesis method. The calcination of zeolite samples led to the formation of well dispersed isolated mononuclear Ag(I) and Agnδ + clusters and a pseudo-…

CO 2 methanation over LDH derived NiMgAl and NiMgAlFe oxides: Improving activity at lower temperatures via an ultrasound-assisted preparation

Michel Obeid, Christophe Poupin, Madona Labaki, Samer Aouad, Sharad Gupta, Haingomalala Lucette Tidahy, Aida Younis, Ferdaous Ben Romdhane, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad, François Delattre

Within the idea to catalyze CO 2 methanation NiMgAl and NiMgAlFe oxides were synthesized by the layered double hydroxide route using co-precipitation and ultrasound-assisted co-precipitation. MgAl and MgAlFe oxides-supported Ni materials prepared by the impregnation method were used as references.…

Fate of Organic Molecules in the Mars Regolith Under UV Radiation Deduced from the MOMIE Laboratory Experiment

Cyril Szopa, Patrice Coll, Fabien Stalport, Olivier Poch, Maguy Jaber, Jean-François Lambert, Laura Rouquette, Jérôme Lasne

Among bioindicators or biosigna- tures, organic molecules present on Mars could be re- trieved in the regolith near the surface due to erosion of rocks and gardening of the soil from meteorites bom- bardment through the Mars history. Once their, the organic molecules are submitted to the harsh…

Ni exsolution from (NiO) (ZrO2)1- for catalytic CO2 valorization

Yuxin Deng, Sharad Gupta, Alexandre Carvalho, Christophe Poupin, Hélène Lauron-Pernot, Josefine Schnee

Nickel (Ni) exsolution from (NiO)x(ZrO2)1-x is presented here as an innovative strategy towards catalytic CO2 hydrogenation, contrasting with conventional catalyst preparation methods such as incipient wetness impregnation and bringing exsolution beyond the field of perovskites. This approach…

Equilibrium and dynamics of single-peptide binding to aluminum oxides: Emphasizing the role of local surface charge and hydrophobicity

Joanne Lê-Chesnais, Christophe Méthivier, Daniela Rodriguez, Christophe Humbert, Jean-François Lambert, Jessem Landoulsi

Understanding the interactions between biomolecules and mineral surfaces is a fundamental challenge at the crossroads of colloid science, surface chemistry, and molecular biophysics. While peptides and amino acids are known to bind a variety of metal oxides, our understanding remains limited…

Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Jingjing Ren, Franck Launay, Richard Villanneau, Anna Proust

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of…

Binding and 2D organization of arginine on Cu(1 1 0)

Roberta Totani, Christophe Méthivier, Dominique Costa, Théo Jaffrelot Inizan, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-arginine adsorption on the Cu(1 1 0) surface in a submonolayer regime. Arginine (ARG) is one of the main components of the tripeptide RGD (arginine-glycine-aspartic acid) commonly used as a linker/binder when engineering…
