Plasma Assisted Catalyst for NOx Remediation from Lean Gas Exhaust

Ahmed Khacef, Patrick da Costa, Gérald Djéga-Mariadassou

A non-thermal plasma (NTP) reactor was coupled with a three-function catalyst in order to verify the nature of the effect of the plasma on the catalytic process. A mixture of NO/O2/hydrocarbons in N2 was used as a lean model exhaust gas composition. The plasma was found to perform two of the three…

LRS-1, a new delaminated phyllosilicate material with high acidity », Chem. Mater., 18(1), 34-40 (2006).

Bachar Zebib, Jean-François Lambert, Juliette Blanchard, Michèle Breysse

Well-crystallized samples of the phyllosilicate magadiite have been synthesized in their sodic form, both purely silicic and with an Al/Si ratio of 30. They have been delaminated by a procedure consisting of CTMA+ swelling in the presence of TPAOH, sonication, and calcination at 700°C to remove the…

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…

The controlled synthesis of metal-acid bifunctional catalysts: The effect of metal:acid ratio and metal-acid proximity in Pt silica-alumina catalysts for n-heptane isomerization

Jadid E Samad, Juliette R Blanchard, Celine R Sayag, Catherine R Louis, John R Regalbuto

Several series of metal-acid bifunctional catalysts with controlled metal:acid ratios and metal site-acid site proximity were evaluated for n-heptane isomerization. Through the study of metal deposition reported in the companion paper, proximity could be achieved at four distinct scales: atomic,…
