Formation and Properties of Silver Clusters

This paper describes the methods to form silver clusters in solid, liquid and gas phases; the properties of clusters such as absorption bands, ESR, redox potential, EA and IP, and their catalytic behaviours in photo splitting water and photographic development processes. The theoretical calculation methods, the calculated properties such as geometry, EA and IP of silver clusters are also discussed. The trends of research on this subject are prospected.
