Influence of the ultrasound power density in the ultrasound-assisted synthesis of Ni-based LDH catalysts for CO2 methanation

Michel Obeid, Christophe Poupin, Madona Labaki, Sharad Gupta, Samer Aouad, François Delattre, Ferdaous Ben Romdhane, François Devred, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad

Ultrasound-assisted co-precipitation method was used to synthesize Ni-LDH based catalysts for CO2 methanation. The influence of ultrasonic irradiation power density (90, 180, 270, and 360 W·L−1) on the physico-chemical properties of the catalysts as well as on their catalytic behavior was studied…

A new concept of a proton battery based on protic ionic liquid

Ekaterina Kurchavova, Julie Chan, Junxian Zhang, Fermin Cuevas, Mickael Mateos, Judith Monnier, Vincent Vivier, Mireille Turmine

Nowadays, the most effective and widely spread energy storage systems are Li-ion batteries. However, they have some drawbacks such as high price, flammability, temperature limitation, reduced availability of Li resources on the Earth, etc.[1]. Thus, the development of new competitive systems is…

Catalytic performances of platinum doped molybdenum carbide for simultaneous hydrodenitrogenation and hydrodesulfurization

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Patrick da Costa, Celine Sayag

The hydrotreating activity of molybdenum carbide doped with platinum (0.3 wt.%) was studied and compared to that of a pure, non-modified Mo2C. 4,6-Dimethyldibenzothiophene (4,6-DMDBT, 300 ppm of S) and carbazole (100 ppm of N) were designated as model compounds and subjected to hydrodesufurization…

Mesoporous materials from zeolite seeds as supports for nickel tungsten sulfide active phases Part 1. Characterization and catalytic properties in hydrocracking reactions

Shuangqin Zeng, Juliette Blanchard, Michèle Breysse, Dadong Li, Hong Nie, Yahua Shib, Xintian Su

MCM-41 aluminosilicate mesostructures (Si/Al = 18) with hexagonal long-range order were assembled from protozeolitic nanoclusters (zeolite seeds) that normally nucleate the crystn. of b-zeolite (BEA). Depending on the duration of the thermal treatment leading to the zeolite seeds, different acidic…

Piezoelectricimmunosensor for direct and rapiddetection of staphylococcal enterotoxin A (SEA) at the ng level

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Jolanda Spadavecchia, Marie-Clarisse Techer, Florence Val, Vincent Le Moigne, M. Gautier, Romain Briandet, Claire-Marie Pradier

A direct, label-free immunosensor was designed for the rapiddetection and quantification of staphylococcal enterotoxin A (SEA) in buffered solutions using quartz crystal microbalance with dissipation (QCM-D) as transduction method. The sensing layer including the anti-SEA antibody was constructed…

Silver species reduction upon exposure of Ag/Al2O3 catalyst to gaseous ethanol: An in situ Quick-XANES study

Elie Sayah, Camille La Fontaine, Valérie Briois, Dalil Brouri, Pascale Massiani

The evolution of supported silver species of a pre-calcined Ag/Al2O3 catalyst was monitored upon thermal treatment under an air flow enriched with 3000 ppm of ethanol (EtOH) using transmission electron microscopy and UV-visible and X-ray absorption spectroscopies. A special focus is put on the…
