METAL PHASES IN ZEOLITE MATRIX - ELECTRIC AND ELECTROCHEMICAL PROPERTIES

Thermal vacuum activation of hydrated silver zeolite forms leads to si lver clusters formation in zeolite framework. The change in electrical conductivity of the Ag form of zeolites is a direct consequence of th e appearance and formation of clusters. The electrochemical behaviour of samples points to the presence of several kinds of silver particles and also to their different location, inside and outside the zeolite. Electric and electrochemical measurements can be of practical importa nce in the investigation of metal clusters in zeolite structures.
