Abstract
Bimetallic supported layered nanoparticles, with an inner nucleus of p latinum and an outer shell of palladium were synthesized by two succes sive chemical vapor deposition runs in a fluidized bed from Pt(Me)(2)( COD) at 120 degrees C and Pd(eta(3)-C3H5)(hfacac) at 60 degrees C, the se remarkable mild conditions allowing in the presence of H-2, to reac h pure metal particles sized between 5 and 15 nn. Both TEM and EDX ana lyses evidenced the layered structure. The preliminary studies on cata lytic dehydrogenation showed the great activity and stability of these bimetallic materials.
