Mesoporous titania with anatase walls by flash induction calcination

Résumé

Induction heating has been used to thermally treat mesostructured TiO2 with hexagonal 20 structure prepared by a combined Liquid Crystalline Template (LCT) and Evaporation Induced Self-Assembly (EISA) synthesis method. Induction treatment induces the decomposition of the structuring agent P123 and the formation of anatase. Highly ordered mesoporous titania with a semi crystalline framework can be obtained very fast, i.e. 5 min at 460 degrees C or 15 min at 300 degrees C. The recovered materials have similar structural, textural properties and photoactivity towards the decomposition of methyl orange than the mesostructured TiO2 obtained after ethanol extraction followed by a calcination at 400 degrees C in a conventional furnace.
