The Raft-Like Structure of Supported PtRu5
Published online by Cambridge University Press: 10 February 2011
Abstract
We have examined supported PtRus 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 15.6Å, 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.
