基本説明
Deals with the basic principles of heterogeneous catalyst preparation, and heightens the practical relevance by providing 10 case studies on such topics as the preparation of zeolites, hydrotreating catalysts, methanol catalysts and gold catalysts.
Full Description
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
