Shape-preserving transformations of porous glass monoliths into MFI-type zeolites by hydrothermal treatments in presence of triisopropyl ammonium bromide and triisopropyl ammonium hydroxide are described. Complete transformations were enabled by addition of a second silicon source to the synthesis solution, here colloidal silica. The impact of parameters such as the pore size and pore-wall thickness of the employed porous glass monoliths, the molar composition of the synthesis solution and the synthesis time on the synthesis product is elucidated.
