Metallic glasses are new materials which present the possibility of preparing new catalysts. From this point of view the authors have been studying the catalytic properties of glassy palladium alloys. The approach has been to employ the molecular probe, (+)-apopinene, which is sensitive to catalytic sites of differing surface coordination. In this present study the authors have examined a number of palladium materials, including splat cooled pure Pd as well as both glassy and crystalline Pd-Si and Pd-Ge prepared by both the shock tube and hammer-and-anvil techniques using the molecular probe (+)-apopinene. Because these materials produce much lower isomerizations than most Pd catalysts, a Pt foil is included as an example of a very low isomerization catalyst. These results can be compared to those obtained over a spectrum of supported and unsupported palladium catalysts for which percentages of exposed Pd atoms are available. 34 references.
