Catalytic 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. — Covers both bulk metals and alloys as well as supported metals metal oxides and metal sulfides — Characterization techniques for zeolites and molecular sieves as well as alumina pillared clays — Concise summaries of major characterization technologies for catalytic materials, including Auger Electron Spectroscopy, Energy-Dispersive X-Ray Spectroscopy, Neutron Activation Analysis, Scanning Electron Microscopy, and Transmission Electron Spectroscopy
