Ashkan Shahmanesh, Davide Romanin, Corentin Dabard, Sang-Soo Chee, Charlie Gréboval, Christophe Methivier, Mathieu G Silly, Julien Chaste, Matthieu Bugnet, Debora Pierucci, Abdelkarim Ouerghi, Matteo Calandra, Emmanuel Lhuillier, Benoit Mahler

We explore the colloidal growth of monolayers of WSSe alloy in their 1T' phase with various Se content. We develop a synthetic procedure leading to reduced aggregation of the flakes. The presence of a narrow band-gap close to the top of the valence band has been evidenced combining…

Acidic Properties of Alkaline-Earth Phosphates Determined by an Experimental-Theoretical Approach

E. Blanco, Q. Gu, J. Couble, L. Martin, T. Onfroy, G. Costentin, Jean-Francois Paul, Carine Michel, S. Loridant

Alkaline-earth phosphates efficient in the dehydration of lactic acid to acrylic acid were previously shown to contain a surface mono/dihydrogen phosphate amorphous layer composed of M2+ cations and both P═O and POH groups. In this work, acidic properties of such a layer were determined combining…

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…

Assessing the potential of xNi-yMg-Al2O3 catalysts prepared by EISA-one-pot synthesis towards CO2 methanation: An overall study

Leila Karam, M. Carmen Bacariza, José David Lopes, Carlos Henriques, Pascale Massiani, Nissrine El Hassan

Mesoporous xNi-yMg-Al2O3 catalysts prepared by combined evaporation induced self-assembly (EISA) and one-pot techniques were tested in CO2 methanation reaction. All calcined/reduced materials were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), N2 physisorption,…

Determination of Integrated Molar Absorption Coefficients for Gaseous Phenol Infrared Bands and Influence of Water Vapor on Their Values

Thomas Onfroy, Olivier Marie

The integrated molar absorption coefficients for ν(OH) (3655 cm-1), δ(OH) (Q branch at 1176 cm-1 or whole bands), [ν(CCring) + δ(OH)] (Q branch at 1344 cm-1 or whole bands) and γ(CH) (752 cm-1) were determined at 342 K, by recording infrared spectra of pure gaseous phenol at different partial…

On the origin of the changes in color of Ag/Al2O3 catalysts during storage

Tesnim Chaieb, Dalil Brouri, Sandra Casale, Jean-Marc Krafft, Tiago da Silva, Cyril Thomas, Laurent Delannoy, Catherine Louis

Despite the large number of catalytic studies involving Ag/Al2O3 catalysts, especially in deNOx reactions, the phenomenon of ageing observed during catalysts storage after preparation by impregnation followed by a calcination treatment, has not been reported earlier and rises questions. The present…

An EPR characterisation of stable and transient reactive oxygen species formed under radiative and non-radiative conditions

E. Richards, D. M Murphy, M. Che

Electron paramagnetic resonance (EPR) spectroscopy is the ideal method of choice when detecting and studying the wide variety of paramagnetic oxygen-centred radicals. For simple diatomic radicals, such as the superoxide (O 2 −) or peroxy (ROO •) species, the CW EPR profile (in particular the g-…
