Characterization of Catalytic MaterialsIsrael E. Wachs, the volume Editor, is Professor of Chemical Engineering at Lehigh University and Director of the Vibrational Spectroscopy Laboratory in the Zettlemoyer Center for Surface Studies. Professor Wachs has done importnat research in heterogeneous catalysis while at Lehigh and, earlier, as a staff member of Exxon Research. Characterization of Catalytic Materials is a modern, comprehensive reference volume covering the analysis of catalytic materials used in commercial applications. This book provides information for understanding the performance of each class of catalytic material and discusses the applications of these materials in different kinds of technologies such as in pollution control, and chemical and petroleum processing. Each chapter is written by individuals who are internationally recognized as experts in their respective areas and is organized for easy reference by catalytic classes, and the types of surface, interface, and bulk characterization that might be sought. Written from the materials perspective, Characterization of Catalytic Materials focuses on the properties to be measured rather than on the techniques to be used. |
