A TEM and UV-visible study of silver reduction by ethanol in Ag-alumina catalysts

Elie Sayah, Dalil Brouri, Yiaho Wu, Andrea Musa, Patrick da Costa, Pascale Massiani

A transmission electron microscopy (TEM) study dedicated to the understanding of dispersion and location of Ag nanospecies in silver-alumina catalysts is reported. A special attention is put on the conditions of powder catalyst deposition on the grids for TEM analysis. When the deposition is…

IR Operando Study of the Acetylene Effect on the NO Reduction Mechanism on Pd–Rh/CeO2–ZrO2 Three-Way Catalyst

T. Onfroy, O. Marie

The impact of acetylene on the NO reduction mechanism was investigated on a Pd–Rh/CeO2–ZrO2 catalyst. Temperature Program Reaction revealed that C2H2 has a detrimental effect on NO reduction by both H2 and CO. Stationary regime perturbed by C2H2 pulse at different temperatures showed that surface…

Influence of the nature of the noble metal on the lean C3H6-assisted decomposition of NO on Ce0.68Zr0.32O2-supported catalysts

Cyril Thomas, Olivier Gorce, Françoise Villain, Gérald Djéga-Mariadassou

The Selective Catalytic Reduction (SCR) of NO assisted by C3H6 is investigated on Ce0.68Zr0.32O2 (CZ)-supported Platinum Group Metals (PGMs: Pd, Rh, Pt) catalysts. This study shows that the order of reactivity of the PGMs supported on CZ is: Pd Pt ≥Rh. The performances of the most active CZ-…

Real time monitoring of the evolution of Ni2+ environment in faujasite upon rehydration by in situ dispersive-EXAFS.

Jean-François Groust, Catherine Pommier, Lorenzo Stievano, François Villain, Christine Giorgetti, François Baudelet, Pascale Massiani

The evolution of both oxygen and framework tetrahedral shells around Ni2+ cations in faujasite upon rehydration can be described in real time thanks to in situ dispersive-EXAFS. Such type of analysis permits precise experimental description of the coordination environment of cations in zeolite…

Giant Exchange-Bias in Polyol-Made CoFe2O4-CoO Core-Shell Like Nanoparticles

Nancy Flores-Martinez, Giulia Franceschin, Thomas Gaudisson, Patricia Beaunier, Nader Yaacoub, Jean-Marc Greneche, Raul Valenzuela, Souad Ammar

Cobalt ferrite ferrimagnetic nanoparticles (NPs) are prepared and used in this work as seeds to grow a thin antiferromagnetic poly- and nanocrystalline CoO shell. The major purpose is to study systematically the characteristics of the as-produced powders, making emphasis on their internal…

Antibacterial properties of glycosylated surfaces: variation of the glucosidal moiety and fatty acid conformation of grafted microbial glycolipids

Claire Valotteau, Sophie Roelants, Dasaiyan Prabhu, Susanne Zibek, Michael Günther, Wim Soetaert, Bernd Everaert, Claire-Marie Pradier, Florence Babonneau, Niki Baccile, Vincent Humblot

Glycosylated surfaces can display antimicrobial properties. It has been shown that sophorolipids can be used to develop biocidal coatings against Gram-positive and Gram-negative bacteria, but with a limited efficiency so far. Therefore, it appears necessary to further investigate the surface…

Optimization and Antibacterial Response of N-Halamine Coatings Based on Polydopamine

Nadia Nazi, Adeline Marguier, Catherine Debiemme-Chouvy, Vincent Humblot

RessouDue to the ability of microorganisms to first adhere to a material surface and then to lead to the formation of a biofilm, it is essential to develop surfaces that have antimicrobial properties. It is well known that N-halamine coatings allow us to prevent or minimize such phenomena. In the…

Enhancement of water remediation by innovative photocatalytic luminous textiles reactor: Performance, kinetic modeling, and mechanistic insights

Sarra Karoui, Aymen Amine Assadi, Achraf Ghorbal, Lotfi Khezami, Achraf Assadi, Sivachandiran Loganathan, Abdeltif Amrane

To address wastewater treatment, a photocatalytic process using luminous-textile has been proposed due to its high efficiency and non-toxicity. In the present work, the photodegradation of Ciprofloxacin (CIP) in the liquid phase was studied in a compact reactor with a luminous-textile catalyst in…
