The updated fourth edition of this successful encyclopedia contains 40% more high-quality content from over 300 international experts in four volumes! Comprehensive, succinct, and unrivaled, it includes all the knowledge scientists need on homogeneous, heterogeneous and biochemical catalysis in easy-to-use, compact entries for over 11,000 keywords in alphabetical order. In this way it explains briefly the important terms for every aspect of catalysis, whether biocatalysis, homogeneous catalysis, heterogeneous catalysis, or such related topics as spectroscopy or analytical methods. These also include abbreviations, brief biographic entries of important scientists who have worked in catalysis, trade names, important catalytic processes, named reactions, and other important keywords in the general field of catalysis. To round this work off, many of the keywords are illustrated and include German and French equivalent terms.
