Chemisorption and Magnetization focuses on particle size determination and on the number of adsorbent atoms affected when any molecule is adsorbed on a surface. This book examines the adsorption of a molecule on the surface of a ferromagnetic solid that produces a change in the magnetization of the solid. Organized into 12 chapters, this book starts with an overview of the experimental methods used for studying chemisorption and magnetization, which are applicable in granulometry. This text then discusses the measurement of saturation magnetization in a ferromagnetic substance in the form of small particles. Other chapters consider the conditions in a typical nickelsilica hydrogenation catalyst. This text examines as well the magnetization at moderate fields and near room temperature. The final chapter deals with the properties and complexities of palladium, platinum, and nickel. Students and researchers interested in heterogeneous catalysis and related areas will find this book extremely useful.
