✦ Synopsis

Zeolites NaY, HUSY and KL were ion-exchanged with a cationic molybdenum sulfide cluster [Mo3S4(H20)9] 4~ with incomplete cubane-type structure and a cationic nickel-molybdenum mixed sulfide duster [Mo3NiS4CI(H20)9] 3+ with complete cubane-type structure. The UV-visible spectra and EXAFS analysis data exhibited that the structure of the molybdenum cluster was maintained after ion exchange. These zeolite catalysts showed activity for benzothiophene hydrodesulfurization; especially, involvement of Ni resulted in great enhancement of the hydrodesulfurization activity.
