 Abstract: Nanoparticles were synthesized using solutions of hydrolyzed TEOS and aluminate TPAOH at room temperature. These nanoparticles were crosslinked by reaction with 1,7- dichlorooctamethyltetrasiloxane. The resulting solid after calcinations is X-ray amorphous, but they show NMR and IR signatures akin to MFI type zeolites. They have microporous properties like a zeolitic structure, but in addition provide a mesopore system resulting from the crosslinking. The acid site strength of aluminosilicate materials is lower than that of HZSM-5, as shown by pyridine desorption at different temperatures followed by IR-spectroscopy.
