Autor: Artium Belet, Bernard Gilbert, Cédric Calberg, Benoît Heinrichs, Christine Jérôme, Géraldine Léonard, Bruno Grignard

Publikováno v: Catalysis Today. 334:140-155

Different types of heterogeneous catalysts designed for a cyclocarbonation reaction between an epoxidized source and CO2 under supercritical conditions have been synthesized. The process implied a quaternization step where a (haloalkyl)trimethoxysila

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 350:32-43

Zinc was coupled with titanium dioxide using different methods. SiO2 and Zn-SiO2 doped TiO2 films, on the one hand, and Zn doped TiO2 on the other hand, have been produced using controlled sol-gel processes by alcoholic, cogelation and aqueous ways.

Towards a large scale aqueous sol-gel synthesis of doped TiO2: Study of various metallic dopings for the photocatalytic degradation of p-nitrophenol

Autor: Benoît Heinrichs, Stéphanie Lambert, Pierre-Yves Olu, Frédéric Boschini, Abdelfattah Mahmoud, Anthony Zubiaur, Julien G. Mahy, Géraldine Léonard

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 329:189-202

In this paper, an easy aqueous sol-gel synthesis developed previously by Mahy et al. [1] is adapted to produce highly active TiO2 catalysts doped with Fe3+, Ag+, Cu2+, Zn2+, Cr3+, Al3+, Mn2+, and Co2+ ions and Pt metallic nanoparticles. Samples are c

Aqueous sol–gel synthesis and film deposition methods for the large-scale manufacture of coated steel with self-cleaning properties

Autor: Dimitri Liquet, Benoît Heinrichs, Catherine Archambeau, Alain Daniel, Julien G. Mahy, Sophie Pirard, David Wicky, Géraldine Léonard

Publikováno v: Journal of Sol-Gel Science and Technology. 81:27-35

A process has been developed to enable the large-scale production of pure TiO2 films deposited on 316L stainless steel in order to get an easy-to-clean surface. This large-scale process requires an easy aqueous sol–gel procedure for the synthesis o

Doped sol–gel films vs. powders TiO 2 : On the positive effect induced by the presence of a substrate

Autor: Els Bruneel, Isabel Van Driessche, Géraldine Léonard, Benoît Heinrichs, Stéphanie Lambert, Quentin Mélotte, Charline Malengreaux

Publikováno v: Journal of Environmental Chemical Engineering. 4:449-459

SiO2 and Ag–SiO2 doped TiO2 films and powders have been produced using a controlled sol–gel process. The dopant has been introduced using an alkoxysilane-functionalized ligand, with or without complexed silver ions. The influence of dopants on ph

Doping TiO2 films with carbon nanotubes to simultaneously optimise antistatic, photocatalytic and superhydrophilic properties

Autor: Simon Remy, Benoît Heinrichs, Géraldine Léonard

Publikováno v: Journal of Sol-Gel Science and Technology. 79:413-425

Pure and multiwall carbon nanotube (MWCNT)-doped titanium dioxide (TiO2) films, synthesised from two sol–gel routes (alcoholic and aqueous) and deposited by dip-coating on glass, have been developed as conductive, photocatalytic and superhydrophili
