Libraries for Secondary Screening

For catalyst preparation all techniques are available that are used in standard lab preparation of inorganic materials. Most of the preparation steps can be automated and can be done in parallel using synthesis robots. In the next sections, the most frequently used preparation routes are discussed. Postsynthesis treatment steps common to many different preparation routes are discussed separately at the end of the section. 

Impregnation (see Chapter 4 for background) is the most frequently used technique in high-throughput preparation due to its apparent simplicity. Table 11.2 summarizes examples of high-throughput impregnation preparation of catalysts. 

A new method that may overcome the drawbacks of traditional precipitation methods is the use of micromixers, which combine excellent mixing (to
