The objectives of our study were to prepare of ZSM-5 and USY-based catalysts by hydrothermal method, containing metallic active phase, deposited by both conventional ionic-exchange or ultrasonic irradiation. Prepared materials were characterized by various physicochemical methods, such as XRD, BET, SEM, UV-VIS and the sorption of ammonia monitored by FT- -IR spectroscopy. The XRD data confirmed pure MFI or USY type structure zeolite. BET and ammonia sorption results have shown that the presented method leads to preparation of highly porous and acidic systems. Metallic active phase was found as cations and oxides with hexagonal and octahedral coordination.
