•Ordered mesoporous titania with anatase framework in short synthesis time.•Simultaneous surfactant removal and wall crystallization by flash induction.•Photocatalytic activity towards methyl orange degradation.•Materials with similar properties than the ones obtained by conventional calcination.
Induction heating has been used to thermally treat mesostructured TiO2 with hexagonal 2D 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 °C or 15 min at 300 °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 °C in a conventional furnace.
