Combines the progress with a discussion of the general aspects of catalyst preparation. This title deals with the basic principles of solid catalyst preparation, explaining the main aspects of sol-gel chemistry and interfacial chemistry, followed by such techniques as co-precipitation and immobilization.This practical book combines recent progress with a discussion of the general aspects of catalyst preparation. The first part deals with the basic principles of solid catalyst preparation, explaining the main aspects of sol-gel chemistry and interfacial chemistry, followed by such techniques as co-precipitation and immobilization. New tools for catalyst preparation research, including microspectroscopy and high-throughput experimentation, are also taken into account. The second part heightens the practical relevance by providing six case studies on such topics as the preparation of zeolites, hydrotreating catalysts, methanol catalysts and gold catalysts.PART I: Basic Principles and Tools GENERAL ASPECTS Importance of Solid Catalysts Development of Solid Catalysts Development of Solid Catalyst Synthesis About this book INTERFACIAL CHEMISTRY Introduction Interfacial and Bulk Deposition The Surface of the Oxidic Supports: Surface Ionization Models The Size and the Structure of the Interface The Arrangement of the Ions Inside the Interface and the Deposition Modes Determining the Mode of Interfacial Depostion and the Surface Speciation/Structure of the Deposited Precursor Species A Case Study: The Deposition of Co(H2=)6 2+ Aqua Complex on the Titania Surface ELECTROSTATIC ADSORPTION Introduction Purely Electrostatic Adsorption Electrostatic Adsorption with Metal Respeciation Electrostatic Adsorption and Ion Exchange Electrostatic Adsorption and Deposition-Precipitation Electrostatic Adsorption and Surface Reaction Electrostatics and Dissolution, Reaction, and Redeposition Electrostatics-Based Design IMPREGNATION AND DRYING Introduction Impregnation Drying The Chemistry Impregnation and Drying of an MoOx/Al2O3 Catalyst SOL-GEL PROCESSING Introduction Physicochemical Basis and Principles of Sol-Gel Processing Application of Sol-Gel Processing for the Preparation of Solid Catalysts DEPOSITION PRECIPITATION Introduction Theory and Practice Mechanistic Studies Case Studies COPRECIPITATION Introduction Basic Principles of Precipitation and Nucleation Raw Materials Precipitation Conditions Process Operation Examples New Developments in Process Monitoring CLUSTERS AND IMMOBILIZATION Introduction The Surface of Common Supports Clusters in Catalysis Reaction with Unmodified Surface ?Ship-in-a-Bottle?
