Characterization of Catalytic MaterialsCatalytic materials are essential to nearly every commercial and industrial chemical process in order to make reaction times faster and more efficient. Understanding the microstructure of such materials is essential to designing improved catalytic properties. This volume in the materials characterization series reviews the more common types characterization methods used for understanding surface and structural properties of most types of commercially used catalytic materials.
