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,…

Catalysis assisted by plasmon, Catalyse assistée par plasmon

Iyad Sarhid

Metallic nanoparticles (NPs) have many applications in catalysis. Some of them (gold, silver, copper) have a visible absorption resulting from the excitation of the surface plasmon by an external electromagnetic field. In this project, we propose to couple the catalytic properties of gold-based…, Les nanoparticules (NPs) métalliques ont de nombreuses applications en catalyse. Certaines d’entre elles (or, argent, cuivre) présentent une absorption dans le visible résultant de l’excitation du plasmon de surface par un champ électromagnétique extérieur. Nous proposons dans ce projet de coupler…

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…

Approach for Plasmonic Based DNA Sensing: Amplification of the Wavelength Shift and Simultaneous Detection of the Plasmon Modes of Gold Nanostructures

Jolanda Spadavecchia, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

In this article, the detection of DNA hybridization taking advantage of the plasmonic properties of gold nanostructures is described. The approach is based on the amplification of the wavelength shift of a multilayered localized surface plasmon resonance (LSPR) sensor interface upon hybridization…

Current Progress in Aqueous Corrosion of Multi-Principal Element Alloys

M. Ghorbani, Z. Li, Y. Qiu, P. Marcus, J. Scully, Oumaïma Gharbi, H. Luo, R. Gupta, Z. Zeng, H. Fraser, M. Taheri, N. Birbilis

While multi-principal element alloys (MPEAs) remain a promising class of materials owing to several attractive mechanical properties, their corrosion performance is also unique. In this concise review, we present an emerging overview of some of the general features related to MPEA corrosion,…

Defects in ZnO nanoparticles obtained by gas-phase syntheses, Défauts dans les nanoparticules de ZnO obtenues par synthèses en phase gazeuse

Miao Zhang

By far, the assignment of defects-related spectroscopic features of zinc oxide is still a matter of great controversy. This is probably due to the variety of possible defects in ZnO as well as to their still uncertain formation energies and positions within the band gap. Uncontrolled measurement…, L’attribution des signatures spectrales liées aux défauts dans l’oxyde de zinc fait encore l’objet de controverses. Ceci est probablement dû à la grande variété de défauts possibles, à l’incertitude de leur niveau d’énergie ainsi que leur énergie de formation dans la bande interdite. De plus, l’…

Promoting Ag/Al2O3 Performance in Low-Temperature H2-C3H6-SCR by Thermal Pretreatment of γ-Alumina in Water

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

The present work highlights for the first time that a thermal treatment of γ-Al2O3 in water at 80 °C for 24 h prior to Ag deposition (Ag/Al2O3-OH) leads to a drastic enhancement of H2-C3H6-SCR performance at low temperature. This enhancement is attributed to the higher NOx coverage on Ag/Al2O3-OH…

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…
