SURFACE PHASE-ANALYSIS OF CATALYSTS AND OTHER DISPERSE MATERIALS USING ELECTROCONDUCTIVITY - THE TVE-CURVES METHOD

The method of thermovacuum electroconductivity (TVE) curves for the an alysis of surface phases in disperse systems is described. The theoret ical basis of the application of electric measurements for the investi gation of the surface of disperse objects is presented. Examples of th e use of the TVE-curves method for characterization of diverse catalyt ic systems and the solving of some problems of heterogeneous catalysis are discussed. The TVE-curves method is an efficient tool for the con trol of the phase-structural state of the surfaces of objects of a sem iconductor type.
