Book excerpt: Heterogeneous Micro and Nanoscale Composites for the Catalysis of Organic Reactions discusses the major properties and applications of heterogeneous micro and nanoscale composites, including surface coating and functionalization capability, effective physical properties, recovery and reusability, biocompatibility and biodegradability. In addition, preparation strategies and essential analytical methods for the characterization of these materials are investigated. The effects of morphology, porosity and sizes of these composites on catalytic activity are also discussed. This book is an important reference source for materials engineers and chemical engineers who are interested in heterogeneous, thin-scaled materials and catalyzed organic synthesis reactions. In addition, this book will help researchers design novel structures and apply them in catalytic applications. - Provides information on the preparation, characterization and applications of catalysis of organic reactions - Outlines the major catalytic applications of heterogenous nanocomposites - Assesses the major challenges of manufacturing heterogenous nanocomposites on an industrial scale
