Abstract

Molecular dynamics calculations of platinum atoms on a graphite surface are performed with different coverages of platinum to simulate the deposition and cluster formation process. The Sutton–Chen many-body potential is used for the Pt–Pt interaction whereas a Steele potential with energy minima representing adsorption sites is used to represent the carbon surface. The cluster size distribution, structure of clusters, effect of loadings, migration, and oxygen adsorption effects are investigated.
