Preparation of Solid Catalysts Black Magic Revealed

Preparation of Solid Catalysts Black Magic Revealed 

The complex and diverse synthesis protocols of solid catalysts sometimes give the impression of alchemy, instead of 21st-century chemistry. The final catalytic properties depend strongly on every step of the preparation, as well as on the purity (and 

Fusion/ alloy leaching (mixed oxides, Raney metals) 

The supports themselves are usually made by the bulk methods. Examples of impregnated catalysts indude the Pd/C hydrogenation catalysts, the Pt/Sn/Al203 dehydrogenation catalysts and the automotive three-way catalysts. There are also catalysts made by hybrid synthesis approaches, e.g., where the active precursors are mixed with a powdered support, and the mixture is then agglomerated.
