Fe-clay-plate as a heterogeneous catalyst in photo-Fenton oxidation of phenol as probe molecule for water treatment

Haithem Bel Hadjltaief, Patrick da Costa, Patricia Beaunier, María Elena Gálvez, Mourad Ben Zina

A novel heterogeneous photo-Fenton plate catalyst was prepared by immobilizing iron species on the surface of natural Tunisian clay. The activity of this structured catalyst was assayed in the degradation of phenol under UV irradiation at two different wavelengths (245 nm, UVC, and 365 nm, UVA,…

Preparation of highly hydrophilic PVA/SBA-15 composite materials and their adsorption behavior toward cationic dye: effect of PVA content

Zakaria Abid, Aboubakr Hakiki, Bouhadjar Boukoussa, Franck Launay, Hadj Hamaizi, Abdelkader Bengueddach, Rachida Hamacha

This work focuses on the preparation of highly hydrophilic polyvinyl alcohol/SBA-15 composites by impregnation method. In order to study the effect of polyvinyl alcohol (PVA) on the structural, textural properties of composites, several percentages of PVA were impregnated into the surface of the…

Characterizing a supported catalyst : a methodological approach

Eric Marceau

The characterization of supported catalysts requires the combination of several physicochemical and spectroscopic techniques in order to investigate the support and active phase composition, morphology and reactivity. The most common techniques used at the laboratory are detailed in this chapter…

On the influence of water traces on the acidity measurement of amorphous aluminosilicates

Juliette Blanchard, Jean-Marc Krafft, Colin Dupont, Céline Sayag, Toshikazu Takahashi, Hiroyuki Yasuda

For the measurement of their acidity, amorphous aluminosilicates are beforehand treated at temperature of 450 • C or higher in order to remove water adsorbed on their surface. We will show in this study that, during the standard course of an acidity measurement by low temperature CO adsorption,…

Mechanistic Investigation of Isopropanol Conversion on Alumina Catalysts: Location of Active Sites for Alkene/Ether Production

Kim Larmier, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Johnny Abboud, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Alcohol dehydration is of prominent relevance in the context of biomass conversion. This reaction can be efficiently catalyzed by alumina surfaces, but the nature of active sites, the mechanisms involved, and the key parameters to tune both the activity and the alkene/ether selectivity remain a…
