Abstract

We have examined supported PtRu₅ specimens by a variety of electron microscopy techniques, including high resolution, analytical and a novel mass-spectroscopic electron microscopy techniques. Analytical electron microscopy results showed that the relative atomic concentration of Pt to Ru for each PtRu₅ cluster is 1 to 5. The average diameter of the clusters was a 15.6 angstrom, and the average number of atoms was measured to be 24 atoms per cluster. The combination of these techniques demonstrate that the PtRu₅ clusters are raft-like on the carbon black support.
