Silica and silica-alumina thin films and monoliths, both possessing hierarchical multimodal pore structure, were synthesized by inducing a phase separation parallel to the sol-gel transition. It was found that it is also possible to obtain zeolitic layers (MFI type) deposited on parent silica or silica-alumina solid monoliths and such composite preparations retain the initial meso/macroporosity as well as texture of the parent material. The morphology of the obtained materials was observed by SEM (monoliths) and AFM (films) whilst the porosity was determined using adsorption/desorption isotherms. Further development and chemical modification of the pore surface should promote the application of well-defined hierarchically porous material into sensor technology.
