Effect of ceria promotion on the catalytic performance of Ni/SBA-16 catalysts for CO 2 methanation

Chao Sun, Patricia Beaunier, Patrick da Costa

The presence of Ce inside the SBA-16 structure promoted the ratio of Ce 3+ and medium basic sites and thus favoured CH 4 formation.

Au-Modified Pd catalyst exhibits improved activity and stability for NO direct decomposition

Taha Elgayyar, Josefine Schnee, Alain Tuel, Laurence Burel, Francoise Bosselet, Yves Schuurman, Frederic C Meunier, Laurent Delannoy, Cyril Thomas

The direct decomposition of NO x at moderate temperatures is a challenge because of the poisoning of the surface of noble metals by oxygen, yet the modification of Pd with Au enables obtaining a highly stable catalyst under an O 2-free feed at 450°C. Care was taken to ensure that the reaction was…

On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…

Potent antimicrobial peptides against Legionella pneumophila and its environmental host, Acanthamoeba castellanii.

Margot Schlusselhuber, Vincent Humblot, Sandra Casale, Christophe Méthivier, Julien Verdon, Matthias Leippe, Jean-Marc Berjeaud

Legionella pneumophila, the major causative agent of Legionnaires' disease, is most often found in the environment in close association with free-living amoebae, leading to persistence, spread, biocide resistance, and elevated virulence of the bacterium. In the present study, we evaluated the…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…

Stability of Binary SAMs Formed by omega-Acid and Alcohol Functionalized Thiol Mixtures

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier, Monica Calatayud, Francesc Illas

A simple model is presented to describe the mixing process of acid- and alcohol-terminated thiol self-assembled monolayers (SAMs) on Au(111). It was found that the low-concentration acid-terminated SAMs are enriched in acid thiol compared with the original solution from which the SAM is made. Due…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…
