The Purpose of Studying Model-Supported Metals

There are clear advantages to the study of model-suf rted systems relative to the study of high surface area support systems (1) the direct examination of metal crystallite location, size, shape, and even structure as a function of time, temperature, and atmosphere (2) direct 

During the past two decades, sophisticated microscopic and spectroscopic techniques have been aj lied to the investigation of sintering and redispersion of model film and single crystal metal-support systems. This review presents and discusses results obtained in these investigations with an emphasis on mechanistic evidence.
