Development of acidic sites in WOx/ZrO2

Thomas Onfroy, Guillaume Clet, Marwan Houalla

Evidence is shown of the appearance of Brønsted acidic sites in WOx/ZrO2 at a given W loading and of a direct correlation between the abundance of ‘strong’ Brønsted acidic sites in these catalysts and propan-2-ol decomposition activity.

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…

Thermal and structural stability of microporous natural clinoptilolite zeolite

Radovan Kukobat, Ranko Škrbić, Pascale Massiani, Karima Baghdad, Franck Launay, Maria Sarno, Claudia Cirillo, Adolfo Senatore, Esad Salčin, Suzana Gotovac Atlagić

Thermal treatment of zeolites prior to their use as adsorbents is needed to remove adsorbed water from zeolite pores, increasing porosity and surface area without inducing structural deterioration. Here, natural zeolite clinoptilolite (CLI) was thermally treated at 378–1073 K in air atmosphere.…

General and Prospective Views on Oxidation Reactions in Heterogeneous Catalysis

Sabine Valange, Jacques C. Védrine

In this review paper, we have assembled the main characteristics of partial oxidation reactions (oxidative dehydrogenation and selective oxidation to olefins or oxygenates, as aldehydes and carboxylic acids and nitriles), as well as total oxidation, particularly for depollution, environmental…

Supported Cu Nanoparticles as Selective and Stable Catalysts for the Gas Phase Hydrogenation of 1,3-Butadiene in Alkene-Rich Feeds

Giorgio Totarella, Rolf Beerthuis, Nazila Masoud, Catherine Louis, Laurent Delannoy, Petra de Jongh

Supported copper nanoparticles are a promising alternative to supported noble metal catalysts, in particular for the selective gas phase hydrogenation of polyunsaturated molecules. In this article, the catalytic performance of copper nanoparticles (3 and 7 nm) supported on either silica gel or…
