Low temperature dry methane reforming over Ce, Zr and CeZr promoted Ni–Mg–Al hydrotalcite-derived catalysts

Radosław Dębek, Maria Elena Galvez, Franck Launay, Monika Motak, Teresa Grzybek, Patrick da Costa

Hydrotalcite derived catalysts promoted with Ce, Zr and CeZr showed considerable activity in dry methane reforming (DMR) at low temperatures (550°C). Direct methane decomposition resulting in the extensive formation of fishbone-type carbon nanofibers was substantially inhibited in the presence of…

The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

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

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

Modelling of a Lean NOx-Trap system with NO/NO2 differentiation and sulfur poisoning

Alexis Manigrasso, Pierre Darcy, Patrick da Costa

One of the challenges in the automotive industry is to develop new vehicles and new technologies with minimal costs. In this context, modeling becomes an important tool for the design of future technologies by reducing the number of tests needed to develop a new exhaust system. With the emergence…

Mechanisms of Adsorption of Short Peptides on Metal and Oxide Surfaces

Vincent Humblot, Jessem Landoulsi, Claire-Marie Pradier

Biointerfaces, involving peptides or proteins and solid surfaces, have been investigated with the aim of controlling the behavior/reactivity of inorganic materials in biological environments. This chapter presents a comprehensive overview of the basic aspects governing the interaction of short…

Enhancing low-temperature activity and durability of Pd-based diesel oxidation catalysts using ZrO2 supports

Mi-Young Kim, Eleni A. Kyriakidou, Jae-Soon Choi, Todd J. Toops, Andrew J. Binder, Cyril Thomas, James E. Parks, Viviane Schwartz, Jihua Chen, Dale K. Hensley

We investigated the impact of ZrO2 on the performance of palladium-based oxidation catalysts with respect to low-temperature activity, hydrothermal stability, and sulfur tolerance. Pd supported on ZrO2 and SiO2 were synthesized for a comparative study. Additionally, in an attempt to maximize the…

Aqueous-Phase Preparation of Model HDS Catalysts on Planar Alumina Substrates: Support Effect on Mo Adsorption and Sulfidation

Cédric Bara, Lucie Plais, Kim Larmier, Elodie Devers, Mathieu Digne, Anne-Félicie Lamic-Humblot, Gerhard D. Pirngruber, Xavier Carrier

The role of the oxide support on the structure of the MoS2 active phase (size, morphology, orientation, sulfidation ratio, etc.) remains an open question in hydrotreating catalysis and biomass processing with important industrial implications for the design of improved catalytic formulations. The…

Charge transport through redox active [H₇P₈W₄₈O₁₈₄]^33- polyoxometalates self-assembled onto gold surfaces and gold nanodots

K. Dalla Francesca, Stéphane Lenfant, M. Laurans, F. Volatron, G. Izzet, Vincent Humblot, C. Methivier, David Guérin, A. Proust, Dominique Vuillaume

Polyoxometalates (POMs) are redox-active molecular oxides, which attract growing interest for their integration into nano-devices, such as high-density data storage non-volatile memories. In this work, we investigated the electrostatic deposition of the negatively charged [H7P8W48O184]33− POM onto…

Plasmonic photothermal destruction of uropathogenic E. coli with reduced graphene oxide and core/shell nanocomposites of gold nanorods/reduced graphene oxide

Kostiantyn Turcheniuk, Charles-Henri Hage, Jolanda Spadavecchia, Aritz Yanguas Serrano, Iban Larroulet, Amaia Pesquera, Amaia Zurutuza, Mariano Gonzalez Pisfil, Laurent Heliot, Julie Bouckaert, Rabah Boukherroub, Sabine Szunerits

The development of non-antibiotic based treatments against bacterial infections by Gram-negative uropathogenic E. coli is a complex task. New strategies to treat such infections are thus urgently needed. This report illustrates the development of pegylated reduced graphene oxide nanoparticles (rGO-…

Synthesis of Well-Defined Dawson-Type Poly(N,N-diethylacrylamide) Organopolyoxometalates

Jennifer Lesage de la haye, Patricia Beaunier, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

An organotin-substituted Dawson-type phosphotungstate was covalently linked to a trithiocarbonate group by postfunctionalization methods. This organopolyoxometalate led to a series of polyoxometalate (POM)–poly(N,N-diethylacrylamide) hybrids in a controlled way through reversible addition–…
