ZSM-5/SBA-15 microporous/mesoporous composites prepared by a microwave-assisted zeolitisation of Al-SBA-15 mesoporous solids

Sami Habib, Franck Launay, Henri El Zakhem, Matjaž Mazaj, Flavien Guenneau, Patricia Beaunier, Dalil Brouri, Nataša Novak Tušar, Venčeslav Kaučič, Antoine Gedeon

ZSM-5/SBA-15 composites with high textural properties were synthesised by a microwave-assisted zeolitisation of Al-SBA-15 in the presence of tetrapropylammonium bromide. The effect of the hydrothermal treatment temperature and of ammonium fluoride, often used as a catalyst, was studied. Resulting…

UV irradiation study of a tripeptide isolated in an argon matrix: A tautomerism process evidenced by infrared and X-ray photoemission spectroscopies.

Eva Mateo-Marti, Claire-Marie Pradier

Matrix isolation is a powerful tool for studying photochemical processes occurring in isolated molecules. In this way, we characterized the chemical modifications occurring within a tri peptide molecule, IGF, when exposed to the influence of Ultraviolet (UV) irradiation. This paper first describes…

A new route for preparing nanoporous Cu–Zn–Ni–Co alloy by electrodeposition and dealloying: Application as electrocatalysts for water reduction

Yuelin Xie, Antoine Miche, Vincent Vivier, Mireille Turmine

<div><p>Nanoporous Cu-Zn-Ni-Co alloys have been prepared on Cu foils by a two-step electrodeposition mechanism in ethylammonium nitrate (EAN), a protic ionic liquid, and ethaline, a deep eutectic solvent (DES). A porous alloy was then produced using a dealloying step. The…

Should W Surface Density of WOx-ZrO2 Catalysts Be Calculated With Respect To the Specific Surface Area of the Sample or That of ZrO2 Only?

Cyril Thomas

On the basis of the critical analysis of the NOx-TPD data obtained on WOx-ZrO2 samples [Law, H. Y.; Blanchard, J.; Carrier, X.; Thomas, C. J. Phys. Chem. C 2010, 114, 9731], this work provides convincing arguments for the first time upon which calculation of W surface density should be done by…
