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

Report
"In short, the volume is precisely what the solid catalysis field needs. It is a convincing and well-written text exploring complex ideas in a coherent and logical way, without simplification. The use of case studies provides valuable contexts for the application of diverse ideas and constructs." ( Current Engineering Practice , 2010)
