Stability of Pd Species on Different Supports

4 Stability of Pd Species on Different Supports - Most studies on Pd-support interactions have focused on alumina-supported catalysts. The situation may be somewhat different on other supports. However, it is important to note that when comparing catalysts with different supports, the effects of particle size and metal-support interactions are inter-related and sometimes cannot be distin- [Pg.16]

A series of Pd catalysts supported on mordenite and ZSM-5 zeolites has exhibited a clear relationship between the activity and the Al203/(Al203 + Si02) ratio. When this ratio and, consequently, the anchoring capacity of the zeolite increases, the activity of the catalyst decreases, i.e., it appears as a general trend that as the interaction with the support increases, Pd becomes less active for combustion. [Pg.18]
