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…

Mesoporous silica supported amine and amine-copper complex for CO2 adsorption: Detailed reaction mechanism of hydrophilic character and CO2 retention

Bouhadjar Boukoussa, Aboubakr Hakiki, Nabil Bouazizi, Ana-Paola Beltrao-Nunes, Franck Launay, Alain Pailleret, Françoise Pillier, Abdelkader Bengueddach, Rachida Hamacha, Abdelkrim Azzouz

Mesoporous silica SBA-15 was functionalized with various amines and then doped with copper II cation (Cu2+). The modified materials were tested for the retention of CO2 at room temperature using temperature-programmed desorption (CO2-TPD). Several parameters affecting the CO2 retention capacity (…

Preparation of two series of VxSiBeta zeolite catalysts with V centres in framework and extra-framework positions and their application in selective oxidation of methanol

Maciej Trejda, Yannick Millot, Karolina Chalupka, Stanislaw Dzwigaj

Two series of V-containing Beta zeolites have been prepared by contacting of the aqueous NH 4 VO 3 solution with two SiBeta zeolites at pH = 2.5 and 6, respectively. Because of the presence in NH 4 VO 3 solution at pH = 2.5 mainly monomeric VO 2 + ions, vanadium have been easily incorporated into…

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.…
