Controlled crystallization of hierarchical monoliths composed of nano-zeolites
Résumé
Micro/macroporous and meso/macroporous amorphous silica monoliths have been prepared and transformed into ZSM-5 nanosheets zeolitic macroporous monoliths. The hierarchized zeolite monoliths have been optimized in term of crystallinity rate by varying durations and temperatures of hydrothermal treatments. Fully crystallized ZSM-5 nanosheets monoliths were obtained after a combination of two consecutive hydrothermal treatments at 150 °C for 5 days with stirring and at 120 °C for 1 day under static conditions.
