Heterogeneous catalytic partial oxidation of lower alkanes (C 1 –C 6 ) on mixed metal oxides

Jacques Védrine

This review paper aims at analysing the state of the art for partial oxidation and oxidative dehydrogenation (ODH) reactions of lower alkanes C1–C6 into olefins and oxygenated products (aldehydes, anhydrides, carboxylic acids) on metal oxide catalysts with cations of variable oxidation state, such…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…

Pseudoaneurysm of anterior tibial artery following a diaphyseal fracture ă of the tibia mimicking a malignant bone tumor

Pierre Sautet, Elie Choufani, Philippe Petit, Franck Launay, Jean-Luc Jouve, Sebastien Pesenti

Pseudoaneurysms of the lower limb are rare and frequently iatrogenics ă complications. Closed traumas are likely to generate lesions of the ă arterial wall, which generally become symptomatic at a later stage. The ă diagnosis of such vascular lesion is difficult because the ă symptomatology and the…

Preparation of Supported Gold Nanoparticles by a Modified Incipient Wetness Impregnation Method

Laurent Delannoy, Nissrine El Hassan, Andrea Musi, Nga Nguyen Le To, Jean-Marc Krafft, Catherine Louis

In this work, we show that if the mere procedure of impregnation of oxide supports with chloroauric acid, which is well-known to lead to large gold particles, is followed by a step of washing with ammonia, small gold particles (3-4 nm) can be obtained after a treatment of calcination at 300 °C on…

Structured hybrid nanoparticles via surface-initiated ATRP of methyl methacrylate from ordered mesoporous silica

F. Audouin, H. Bias, P. Pasetto, P. Beaunier, C. Boissiere, C. Sanchez, M. Save, B. Charleux

Structured hybrid nanoparticles were synthesized via surface-initiated atom transfer radical polymerization of MMA from ordered mesoporous silica (QMS) nanoparticles with various morphologies. The design of the QMS particles was adjusted to target either spherical core-shell or cylindrical…

Drastic Au(111) Surface Reconstruction upon Insulin Growth Factor Tripeptide Adsorption

Vincent Humblot, Anne Vallee, Ahmed Naitabdi, Frederik Tielens, Claire-Marie Pradier

Adsorption of biomolecules at metal surfaces often creates two-dimensional ordering of the adlayers. However, metal substrate reconstruction is less commonly observed, unless upon annealing of the molecule−surface system. Here, we report on the drastic room-temperature reconstruction of the Au(111…

Synthesis and Treatment Parameters for Controlling Metal Particle Size and Composition in Cu/ZnO MaterialsFirst Evidence of Cu3Zn Alloy Formation

Salim Derrouiche, Hélène Lauron-Pernot, Catherine Louis

This paper deals with the study of the conditions of obtention of small metal copper particles on ZnO using easy synthesis methods and activation treatments, which were found "efficient" for the preparation of copper particles on silica, that is, deposition-precipitation with urea and…

Ag–Ni bimetallic SiBEA zeolite as an efficient catalyst of hydrodechlorination of 1,2-dichloroethane towards ethylene

A Śrębowata, I Zielińska, R Baran, G Słowik, S Dzwigaj

Dealuminated form of BEA zeolite with Si/Al ratio of 1500 was used for the synthesis of Ag2.0SiBEA, Ni2.0SiBEA and Ag2.0Ni2.0SiBEA by two-step postsynthesis method. The calcination of zeolite samples led to the formation of well dispersed isolated mononuclear Ag(I) and Agnδ + clusters and a pseudo-…

Effect of the activation temperature on the state of gold supported on titania: An FT-IR spectroscopic study

Tz. Venkov, Katia Fajerwerg, L. Delannoy, Hr. Klimev, K. Hadjiivanov, C. Louis

The effect of the pre-treatment conditions on the evolution of gold species on an Au/TiO2 sample prepared by deposition–precipitation with urea has been followed by FT-IR spectroscopy of adsorbed CO. Gold is in the form of Au3+ species on the as-prepared sample and is not affected by evacuation at…
