摘要：

In this review we summarize the results of the molecular dynamics simulations performed by our recently developed code on the simulation of the formation process of metal-oxide supported ultrafine metal particles. First we present our investigations on the formation processes of ultrafine gold particles on the metal-oxide surface. We also show the effect of substrate temperature and deposition rate of the Au particles on the generated gold clusters. Furthermore, we investigate the influence of different kinds of surface defects on the formation process of supported Au clusters and the role of these effects in the production and design of highly dispersed ultrafine Au particles.
