Abstract

Pre-shaped amorphous silica and silica/alumina monoliths containing an extensive system of meso-/macropores were used as parent solids for the preparation of a new type of hierarchical porous systems. Impregnation of the monolith pore walls with a template solution and subsequent hydrothermal recrystallization resulted in the formation of materials consisting of amorphous silica or silica/alumina carcass covered with a thin layer of the MFI crystals. The differences in the porous structure of the parent monoliths appeared to have critical effect on the porosity and deposition of the zeolitic phase in the prepared composites. The results of characterisation of both parent and modified monoliths carried out by XRD, N2 adsorption and SEM are discussed.
